Investment Goals and Style
Prudential Municipal Series Fund/Connecticut Money
Market Series seeks to provide the highest level of
current income that is exempt from Connecticut
State and federal income taxes, consistent with
liquidity and the preservation of capital. The
Series intends to invest in a portfolio of short-
term municipal debt securities with maturities of
13 months or less from the state of Connecticut,
its municipalities, local governments, and other
qualifying issuers (such as Puerto Rico, Guam, and
the U.S. Virgin Islands). There can be no assurance
that the Series will achieve its investment
objective.

Message From the Fund's President   As of April 17, 2000

Dear Shareholder
The Federal Reserve increased short-term interest
rates twice to slow U.S. economic growth and fend
off higher inflation during the six months that
ended on February 29, 2000. Prudential's Money
Markets Sector team worked hard to anticipate these
changes in U.S. monetary policy, and acted quickly
to take advantage of good investment opportunities
that emerged as  Connecticut money market yields
rose.

As a result, Prudential Municipal Series
Fund/Connecticut Money Market Series maintained a
$1.00 net asset value per share, and provided a
competitive yield. On February 29, 2000, the
Series' seven-day current yield was 2.95%, compared
with 2.87% for the average Connecticut money market
fund as tracked by iMoneyNet, Inc. The following
report takes a closer look at developments in the
municipal money market sector during the six-month
review period, and explains how the Series was
positioned throughout.

High-quality investments can help reduce risk
Having a conservative, high-quality investment
alternative, such as a money market fund, made good
sense for investors who were concerned about
volatile conditions in financial markets. Indeed,
investors may do well to consider investing in a
money market fund as part of their overall
investment strategy. For any of life's unexpected
events, it is reassuring to have quick access to
your money and an investment vehicle that
emphasizes safety of principal and liquidity.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

Sector Team Leader) and Richard S. Lynes

Fed tried to curb U.S. economic growth
Shortly before the Series' fiscal half year began
on September 1, 1999, the Federal Reserve increased
the federal funds rate (what U.S. banks charge each
other for overnight loans) by a quarter of a
percentage point to 5.25% from 5.00%. It also
raised the rate at which banks can borrow from the
Federal Reserve system (known as the discount rate)
to 4.75% from 4.50%.

The short-term rate hike rippled through the U.S.
economy, increasing borrowing costs for consumers
and businesses. In this way, the Fed hoped to rein
in the brisk pace of U.S. economic growth and avert
a buildup in inflationary pressures. Mounting
inflation is particularly hard on people who live
on fixed incomes, because their buying power
declines if their incomes are not adjusted for the
rise in prices.

We bought before the rate hike
Although we believed that the Fed would continue to
tighten monetary
policy, we purchased longer-term Connecticut money
market securities
in September 1999 that seemed to offer good value
at that time. Our purchases extended the Series'
weighted average maturity (WAM), which remained
longer than that of the average comparable fund
during September and early October 1999. (WAM is a
measurement tool that determines a portfolio's
sensitivity to changes in the level of interest
rates. It takes into account the maturity level of
each security held in a portfolio.)

Prudential Municipal Series Fund   Connecticut Money Market Series
Performance Review

In hindsight, the Series would have been better
served had we reduced its WAM in September by
purchasing shorter-term Connecticut money market
securities. As these securities matured, we could
have reinvested the money in higher-yielding
Connecticut money market securities that became
available after the Fed again raised short-term
rates on November 16, 1999. The central bank
increased the federal funds rate to 5.50% and its
discount rate to 5.00%.

New year brought good buying opportunities
We again extended the Series' WAM in January 2000
by purchasing two kinds of bonds, both of which
provided attractive yields and were good
alternatives to tax-exempt notes and other
conventional municipal money market securities. We
bought one-year "prerefunded" bonds that are backed
by direct obligations of the U.S. government. We
also purchased one-year bonds that were rated AAA
because their interest and principal payments are
insured by a major bond insurance company. The
insured short-term bonds provided solid yields.
Owning these insured municipal bonds offering
higher yields met our fundamental buy-and-hold
strategy.

Fed stepped on brakes again
The year 2000 also brought renewed efforts by the
Fed to check the powerful U.S. economy, which sped
along at a more than 7% annualized pace in the
final three months of 1999. On February 2, 2000,
the central bank raised the federal funds rate to
5.75% and its discount rate to 5.25%. February
marked the 107th consecutive month of the economic
expansion, making it the longest in U.S. history.
In the statement released when it changed monetary
policy, the Fed warned that further rate hikes
might be necessary to keep the U.S. economy from
overheating.

Looking Ahead
True to its word, the Fed again raised the federal
funds rate to 6.00% and the discount rate to 5.50%
on March 21, 2000. As the U.S. economy continues to
grow rapidly, we believe this may not be the last
time the Fed will take action this year.

With the approach of the tax season, we intend to
again increase the Series' exposure to very short-
term municipal money market securities in order to
accommodate seasonal cash outflows that usually
occur as shareholders pay their income taxes.
Adopting this strategy should position the Series
to lock in higher yields that become available as
the supply of municipal money market securities
balloons during the tax season.

       Prudential Municipal Series Fund      Connecticut Money Market Series
             Notes to Financial Statements (Unaudited)

      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of 11
series. The monies of each series are invested in separate, independently
managed portfolios. The Connecticut Money Market Series (the 'Series') commenced
investment operations on August 5, 1991. The Series is nondiversified and seeks
to provide the highest level of income that is exempt from Connecticut state and
federal income taxes with the minimum of risk by investing in 'investment grade'
tax-exempt securities having a maturity of thirteen months or less and whose
ratings are within the two highest ratings categories by a nationally recognized
statistical rating organization, or if not rated, are of comparable quality. The
ability of the issuers of the securities held by the Series to meet their
obligations may be affected by economic developments in a specific state,
industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.
      Securities Valuations:    Portfolio securities of the Series are valued at
amortized cost, which approximates market value. The amortized cost method of
valuation involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of any discount or
premium.
      All securities are valued as of 4:30 p.m., New York time.
      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of investments are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and accretes
original issue discount on portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.
      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason, no federal income tax provision is
required.
      Dividends:    The Series declares daily dividends from net investment
income and net realized short-term capital gains or losses. Payment of dividends
is made monthly. Income distributions and capital gain distributions are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles.
                                                                          13

             Notes to Financial Statements (Unaudited) Cont'd.

      Custody Fee Credits:    The Series has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.

Note 2. Agreements    The Fund has a management agreement with Prudential
Investments Fund Management LLC ('PIFM'). Pursuant to this agreement, PIFM has
responsibility for all investment advisory services and supervises the
subadviser's performance of such services. PIFM has entered into a subadvisory
agreement with The Prudential Investment Corporation ('PIC'); PIC furnishes
investment advisory services in connection with the management of the Fund. PIFM
pays for the services of the PIC, the cost of compensation of officers of the
Fund, occupancy and certain clerical and bookkeeping costs of the Fund. The Fund
bears all other costs and expenses.
      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.
      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Fund. The
Fund compensates PIMS for distributing and servicing the Fund's shares pursuant
to the plan of distribution regardless of expenses actually incurred by them.
The Series reimburses PIMS for distributing and servicing the Series' shares
pursuant to the plan of distribution at an annual rate of .125 of 1% of the
Series' average daily net assets. The distribution fee is accrued daily and
payable monthly.
      PIFM, PIC and PIMS are indirect, wholly owned subsidiaries of The
Prudential Insurance Company of America.
Note 3. Other Transactions with Affiliates    Prudential Mutual Fund Services
LLC ('PMFS'), a wholly owned subsidiary of PIFM, serves as the Fund's transfer
agent. During the six months ended February 29, 2000, the Series incurred fees
of approximately $10,000 for the services of PMFS. As of February 29, 2000,
approximately $1,700 of such fees were due to PMFS. Transfer agent fees and
expenses in the Statement of Operations also include certain out-of-pocket
expenses paid to nonaffiliates.

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/Florida Series'
investment objective is to maximize current income
that is exempt from federal income taxes,
consistent with the preservation of capital, and to
invest in securities that will enable its shares to
be exempt from the Florida intangibles tax.
However, certain shareholders may be subject to the
federal alternative
minimum tax (AMT) because some of the Series' bonds
are AMT eligible. There can be no assurance the
Series will achieve its investment objective.

Message From the Fund's President   As of April 17, 2000

(PHOTO)
Dear Shareholder
The Class A shares of Prudential Municipal Series
Fund/Florida Series had a negative return of 0.72%
during its fiscal half year that ended February 29,
2000. For the same period, the return on the
Series' benchmark Lipper Average was a negative
1.36%. After the initial sales charge, the Class A
shares' return was a negative 3.70%. Prices of
municipal bonds declined primarily because
investors required higher yields in light of two
short-term rate increases implemented by the
Federal Reserve during our review period to slow
the rapid pace of U.S. economic growth.

Staying the course amid ups and downs of financial
markets
Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

(PHOTO)  (PHOTO)  Portfolio Managers Evan Lamp (Municipal Bonds
Sector Team Leader) and Scott Diamond

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest
rates by the Federal Reserve and sales of municipal
bonds by investors who wanted to realize tax losses
pressured the prices of tax-exempt debt securities.
Given this bearish trend, we positioned the Series
so that it would be less vulnerable to the decline
in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also
engineered two quarter-point increases that raised
its discount rate on loans to banks from the
Federal Reserve system to 5.25% by February 2000.
As short-term rates rose, investors required higher
yields on both short- and long-term municipal
bonds, which caused their prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvest in new bonds or other bond funds
with a lower cost basis for tax purposes (due to
the higher level of yields). This is called "tax
loss swapping." In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

Past performance is not indicative of future

fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their
original cost.

LLC and Lipper Inc. The cumulative total returns do
not take into account sales charges. The average
annual total returns do take into account
applicable sales charges. The Series charges a
maximum front-end sales charge of 3% for Class A
shares and a declining contingent deferred sales
charge (CDSC) of 5%, 4%, 3%, 2%, 1%, and 1% for six
years for Class B shares. Class B shares will
automatically convert to Class A shares, on a
quarterly basis, approximately seven years after
purchase. Class C shares are subject to a front-end
sales charge of 1% and a CDSC for 18 months. Class
Z shares are not subject to a sales charge or
distribution and service (12b-1) fees. Without
waiver of management fees and/or expense
subsidization, the Series' cumulative and average
annual total returns would have been lower, as
indicated in parentheses ( ).

Prudential Municipal Series Fund   Florida Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase its distribution
yield in this rising-interest-rate environment.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally
provides some degree of protection by making the
portfolio less sensitive to the rise in bond
yields. (Duration measures how much a portfolio's
bonds will fluctuate in price for a given change in
interest rates. It is expressed in years.) The
Series' share classes, without sales charges
factored in, performed better than its benchmark
Lipper Average, which does not consider sales
charges. This occurred largely because we kept its
duration shorter than average for most of its
fiscal half year.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

The Series' relative performance was also enhanced
because it owns bonds issued by the Daughters of
Charity for the Sacred Heart Hospital. During our
review period, these debt securities rallied
because they were prerefunded. This means the bonds
are now backed by an escrow of direct obligations
of the U.S. government whose interest and principal
will be used to pay off the bonds at their first
call date.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for
investors who might want to buy them. Here's how it
works: When yields climb beyond a certain point for
every municipal bond, the market discount on that
bond may become subject to ordinary income taxes
for new buyers. This lowers the value of the bond
because new buyers would want to purchase the bond
cheaply enough to compensate for the greater tax
liability.

Looking Ahead
Shortly after our six-month review period ended,
the Fed engineered
another quarter-point rate hike that raised its
target for the federal funds rate to 6.00% and its
discount rate to 5.50%. We believe the Fed's
efforts to tighten monetary policy will slow the
U.S. economic expansion in 2000 from its 7.30%
annual pace in the fourth quarter of 1999.
Moderating economic growth could help bolster the
performance of municipal bonds, but detract from
the performance of equities.

Meanwhile, the powerful U.S. economic expansion has
improved the credit quality of many state and local
governments and reduced their borrowing needs,
allowing them to issue fewer bonds. The supply of
new municipal bonds has also decreased because the
rising-interest-rate environment provided less
opportunity for issuers to save money by replacing
older higher-coupon bonds with new lower-coupon
bonds. With the declining supply, if investor
demand remains strong, the tax-exempt bond market
could perform better than other U.S. fixed-income
markets in 2000.

      Prudential Municipal Series Fund, (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of 11
series. The monies of each series are invested in separate, independently
managed portfolios. The Florida Series (the 'Series') commenced investment
operations on December 28, 1990. The Series is nondiversified and seeks to
achieve its investment objective of providing the maximum amount of income that
is exempt from federal income taxes with the minimum of risk, and investing in
securities which will enable its shares to be exempt from the Florida
intangibles tax by investing in 'investment grade' tax-exempt securities whose
ratings are within the four highest ratings categories by a nationally
recognized statistical rating organization or, if not rated, are of comparable
quality. The ability of the issuers of the securities held by the Series to meet
their obligations may be affected by economic developments in a specific state,
industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.

      Securities Valuations:    The Series values municipal securities
(including commitments to purchase such securities on a 'when-issued' basis) on
the basis of prices provided by a pricing service which uses information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining values. If market quotations are not readily available
from such pricing service, a security is valued at its fair value as determined
under procedures established by the Trustees.

      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost.

      All securities are valued as of 4:15 p.m., New York time.

      Financial Futures Contracts:    A financial futures contract is an
agreement to purchase (long) or sell (short) an agreed amount of securities at a
set price for delivery on a future date. Upon entering into a financial futures
contract, the Series is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Series each day, depending on
the daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
    16

loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

      The Series invests in financial futures contracts in order to hedge its
existing portfolio securities, or securities the Series intends to purchase,
against fluctuations in value caused by changes in prevailing interest rates.
Should interest rates move unexpectedly, the Series may not achieve the
anticipated benefits of the financial futures contracts and may realize a loss.
The use of futures transactions involves the risk of imperfect correlation in
movements in the price of futures contracts, interest rates and the underlying
hedged assets.

      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and accretes
original issue discount on portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.

      Net investment income (other than distribution fees) and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.

      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all of its net income to
shareholders. For this reason no federal income tax provision is required.

      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends is made monthly. Distributions of
net capital gains, if any, are made annually.

      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.

      Custody Fee Credits:    The Fund has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.

Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment
                                                                          17

Corporation ('PIC'). PIC furnishes investment advisory services in connection
with the management of the Fund. PIFM pays for the services of PIC, the cost of
compensation of officers of the Fund, occupancy and certain clerical and
bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

      The management fee paid to PIFM is computed daily and payable monthly, at
an annual rate of .50 of 1% of the average daily net assets of the Series.

      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Class A,
Class B, Class C and Class Z shares of the Fund. The Fund compensates PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares,
pursuant to plans of distribution (the 'Class A, B and C Plans') regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly. No distribution or service fees are paid to PIMS as distributor
for Class Z shares of the Fund.

      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and .75 of 1% of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plans were .25 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively,
for the six months ended February 29, 2000.

      PIMS has advised the Series that they have received approximately $5,800
and $100 in front-end sales charges resulting from sales of Class A and C
shares, respectively during the six months ended February 29, 2000. From these
fees, PIMS paid such sales charges to affiliated broker-dealers, which in turn
paid commissions to salespersons and incurred other distribution costs.

      PIMS has advised the Series that for the six months ended February 29,
2000, they received approximately $32,800 and $300 in contingent deferred sales
charges imposed upon certain redemptions by Class B and Class C shareholders,
respectively.

      PIFM, PIMS and PIC are indirect, wholly owned subsidiaries of The
Prudential Insurance Company of America ('Prudential').

      The Fund, along with other affiliated registered investment companies (the
'Funds'), entered into a syndicated credit agreement ('SCA') with an
unaffiliated lender. The maximum commitment under the SCA is $1 billion and
interest on any borrowings will be at market rates. For the period
3/11/99-3/9/00, the commitment fee on the unused portion of the credit facility
was .065 of 1%. Subsequent to March 9, 2000, the SCA was renewed with a maximum
commitment of $1 billion at a commitment fee of .080 of 1% of the unused portion
of the credit facility. The expiration date of the SCA is March 9, 2001. The
commitment fee is accrued and paid

quarterly on a pro rata basis by the Funds. Prior to March 11, 1999, the Funds
had a credit agreement with a mximum commitment of $200,000,000. The commitment
fee was .055 of 1% on the unused portion of the credit facility. The Fund did
not borrow any amounts during the six months ended February 29, 2000. The
purpose of the credit agreements is to serve as an alternative source of funding
for capital share redemptions.

Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $12,700 for the services of
PMFS. As of February 29, 2000, approximately $2,100 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations include
certain out-of-pocket expenses paid to nonaffiliates.

Note 4. Portfolio Securities
Purchases and sales of portfolio securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000 were $12,501,019 and
$18,766,932, respectively.

      The cost basis of investments for federal income tax purposes at February
29, 2000 was substantially the same as for financial reporting purposes and
accordingly, net unrealized depreciation of investments for federal income tax
purposes was $806,349 (gross unrealized appreciation--$2,763,904 gross
unrealized depreciation--$3,570,253).

      The Series elected, for United States federal income tax purposes, to
treat short-term capital losses of $44,975 and long-term capital losses of
$54,800 incurred in the ten months ended August 31, 1999 as having been incurred
in the current fiscal year.

Note 5. Capital
The Series offers Class A, Class B, Class C and Class Z shares. Class A shares
are sold with a front-end sales charge of up to 3%. Class B shares are sold with
a contingent deferred sales charge which declines from 5% to zero depending on
the period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% during the first 18 months. Class B shares will automatically
convert to Class A shares on a quarterly basis approximately seven years after
purchase. Special exchange privileges are also available for shareholders who
qualify to purchase Class A shares at net asset value. Class Z shares are not
subject to any sales or redemption charge and are offered exclusively for sale
to a limited group of investors. The Fund
                                                                          19

Getting the Most From Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read
this--they don't read annual and semiannual reports.
It's quite understandable. These annual and
semiannual reports are prepared to comply with
federal regulations, and are often written in
language that is difficult to understand. So when
most people run into those particularly daunting
sections of these reports, they don't read them.
We think that's a mistake
At Prudential Mutual Funds, we've made some changes
to our report to make it easier to understand and
more pleasant to read. We hope you'll find it
profitable to spend a few minutes familiarizing
yourself with your investment. Here's what you'll
find in the report:
Performance at a Glance
Since an investment's performance is often a
shareholder's primary concern, we present
performance information in two different formats.
You'll find it first on the "Performance at a
Glance" page where we compare the Fund and the
comparable average calculated by Lipper, Inc., a
nationally recognized mutual fund rating agency. We
report both the cumulative total returns and the
average annual total returns. The cumulative total
return is the total amount of income and
appreciation the Fund has achieved in various time
periods. The average annual total return is an
annualized representation of the Fund's
performance. It gives you an idea of how much the
Fund has earned in an average year for a given time
period. Under the performance box, you'll see
legends that explain the performance information,
whether fees and sales charges have been included
in returns, and the inception dates for the Fund's
share classes.
See the performance comparison charts at the back
of the report for more performance information.
Please keep in mind that past performance is not
indicative of future results.

(800) 225-1852

Performance review
The portfolio manager, who invests your money for
you, reports on
successful--and not-so-successful--strategies in this
section of your report. Look for recent purchases
and sales here, as well as information about the
sectors the portfolio manager favors, and any
changes that are on the
drawing board.
Portfolio of Investments
This is where the report begins to appear
technical, but it's really just a
listing of each security held at the end of the
reporting period, along with valuations and other
information. Please note that sometimes we discuss
a security in the Performance Review that doesn't
appear in this listing because it was sold before
the close of the reporting period.
Statement of Assets and Liabilities
The balance sheet shows the assets (the value of
the Fund's holdings),
liabilities (how much the Fund owes), and net
assets (the Fund's
equity, or holdings after the Fund pays its debts)
as of the end of the reporting period. It also
shows how we calculate the net asset value per
share for each class of shares. The net asset value
is reduced by payment of your
dividend, capital gain, or other distribution, but
remember that the money or new shares are being
paid or issued to you. The net asset value
fluctuates daily, along with the value of every
security in the portfolio.
Statement of Operations
This is the income statement, which details income
(mostly interest and
dividends earned) and expenses (including what you
pay us to manage your money). You'll also see
capital gains here--both realized and unrealized.

<PAGE>

Prudential Municipal Series Fund   Florida Series
Getting the Most From Your Prudential Mutual Fund

Statement of Changes in Net Assets
This schedule shows how income and expenses
translate into changes
in net assets. The Fund is required to pay out the
bulk of its income to shareholders every year, and
this statement shows you how we do it (through
dividends and distributions) and how that affects
the net assets. This statement also shows how money
from investors flowed into and out of the Fund.
Notes to Financial Statements
This is the kind of technical material that can
intimidate readers, but it does contain useful
information. The Notes provide a brief history and
explanation of your Fund's objectives. In addition,
they outline how Prudential Mutual Funds prices
securities. The Notes also explain who manages and
distributes the Fund's shares and, more
importantly, how much they are paid for doing so.
Finally, the Notes explain how many shares are
outstanding and the number issued and redeemed over
the period.
Financial Highlights
This information contains many elements from prior
pages, but on a
per-share basis. It is designed to help you
understand how the Fund
performed, and to compare this year's performance
and expenses to those of prior years.
Independent Auditor's Report
Once a year, an outside auditor looks over our
books and certifies that the information is fairly
presented and complies with generally accepted
accounting principles.
Tax Information
This is information that we report annually about
how much of your total return is taxable. Should
you have any questions, you may want to consult a
tax adviser.

<PAGE>

www.prudential.com         (800) 225-1852

Performance Comparison
These charts are included in the annual report and
are required by the Securities Exchange Commission.
Performance is presented here as a hypothetical
$10,000 investment in the Fund since its inception
or for 10 years (whichever is shorter). To help you
put that return in context, we
are required to include the performance of an
unmanaged, broad-based securities index as well.
The index does not reflect the cost of buying the
securities it contains or the cost of managing a
mutual fund. Of course, the index holdings do not
mirror those of the Fund--the index is a broad-based
reference point commonly used by investors to
measure how well they are doing. A definition of
the selected index is also provided. Investors
cannot invest directly in an index.

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:
There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!
Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.
Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Message From the Fund's President    As of April 17, 2000

(PHOTO)
Dear Shareholder
The Class A shares of Prudential Municipal Series
Fund/Massachusetts Series had a negative return of
1.16% during its fiscal half year that ended February 29,
2000. For the same period, the return on the
Series' benchmark Lipper Average was a negative
1.21%. After the initial sales charge, the Class A
shares' return was a negative 4.12%. Prices of
municipal bonds declined primarily because
investors required higher yields in light of two
short-term rate increases implemented by the
Federal Reserve during our review period to slow
the rapid pace of U.S. economic growth.

Staying the course amid ups and downs of financial
markets
Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

(PHOTO)  (PHOTO) Portfolio Managers Evan Lamp (Municipal Bonds
Sector Team Leader) and Lorely Machin

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest
rates by the Federal Reserve and sales of municipal
bonds by investors who wanted to realize tax losses
pressured the prices of tax-exempt debt securities.
Given this bearish trend, we positioned the Series
so that it would be less vulnerable to the decline
in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also engineered two quarter-point increases that raised
its discount rate on loans to banks from the
Federal Reserve system to 5.25% by February 2000.
As short-term rates rose, investors required higher
yields on both short- and long-term municipal
bonds, which caused their prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvest in new bonds or other bond funds
with a lower cost basis for tax purposes (due to
the higher level of yields). This is called "tax
loss swapping." In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

LLC and Lipper Inc. The cumulative total returns do
not take into account sales charges. The average
annual total returns do take into account
applicable sales charges. The Series charges a
maximum front-end sales charge of 3% for Class A
shares and a declining contingent deferred sales
charge (CDSC) of 5%, 4%, 3%, 2%, 1%, and 1% for six
years for Class B shares. Class B shares will
automatically convert to Class A shares, on a
quarterly basis, approximately seven years after
purchase. Class C shares are subject to a front-end
sales charge of 1% and a CDSC for 18 months. Class
Z shares are not subject to a sales charge or
distribution and service
(12b-1) fees. Without waiver of management fees
and/or expense subsidization, the Series'

Prudential Municipal Series Fund    Massachusetts Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase distribution
yield in this rising-interest-rate environment.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally provides some degree of
protection by making the portfolio less sensitive
to the rise in bond yields. (Duration measures how
much a portfolio's bonds will fluctuate in price
for a given change in interest rates. It is
expressed in years.) We kept the Series' duration
shorter than average for much of our fiscal half
year.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

We also maintained a considerable exposure to
prerefunded bonds, which made up 26% of the Series'
total investments as of February 29, 2000. Prices
of prerefunded bonds held up better due to their
high coupon rates and shorter-term maturities.

Massachusetts bonds upgraded
During our six-month review period, Moody's
Investors Service upgraded the Commonwealth of
Massachusetts' general obligation bonds to Aa2 from
Aa3. Moody's cited the economic strength of
Massachusetts that would enable it to accommodate a
lower tax rate if residents of the commonwealth
voted to cut taxes later in the year. We took
advantage of the improvement in rating by selling
our uninsured Massachusetts general obligation
bonds. As of February 29, 2000, Massachusetts
general obligation bonds accounted for nearly 7.00%
of the Series' total investments, its largest
position.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for
investors who might want to buy them. Here's how it
works: When yields climb beyond a certain point for
every municipal bond, the market discount on that
bond may become subject to ordinary income taxes
for new buyers. This lowers the value of the bond
because new buyers would want to purchase the bond
cheaply enough to compensate for the greater tax
liability.

Looking Ahead
The powerful U.S. economic expansion has improved
the credit quality of many state and local
governments and reduced their borrowing needs,
allowing them to issue fewer bonds. The supply of
new municipal bonds has also decreased because the
rising-interest-rate environment has provided less
opportunity for issuers to save money by replacing
older higher-coupon bonds with new lower-coupon
bonds. With the declining supply, if investor
demand remains strong, the tax-exempt bond market
should perform better than other U.S. fixed-income
markets in 2000.

       Prudential Municipal Series Fund      Masschusetts Series
             Notes to Financial Statements (Unaudited)

      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of 11
series. The monies of each series are invested in separate, independently
managed portfolios. The Massachusetts Series (the 'Series') commenced investment
operations in September, 1984. The Series is diversified and seeks to achieve
its investment objective of obtaining the maximum amount of income exempt from
federal and applicable state income taxes with a minimum of risk by investing in
'investment grade' tax-exempt securities whose ratings are within the four
highest ratings categories by a nationally recognized statistical rating
organization or, if not rated, are of comparable quality. The ability of the
issuers of the securities held by the Series to meet their obligations may be
affected by economic developments in a specific state, industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.

      Securities Valuations:    The Series values municipal securities
(including commitments to purchase such securities on a 'when-issued' basis) on
the basis of prices provided by a pricing service which uses information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining values. If market quotations are not readily available
from such pricing service, a security is valued at its fair value as determined
under procedures established by the Trustees.

      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost which approximates market value.

      All securities are valued as of 4:15 p.m., New York time.

      Financial Futures Contracts:    A financial futures contract is an
agreement to purchase (long) or sell (short) an agreed amount of debt securities
at a set price for delivery on a future date. Upon entering into a financial
futures contract, the Series is required to pledge to the broker an amount of
cash and/or other assets equal to a certain percentage of the contract amount.
This amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Series each day, depending on
the daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. The Series invests in financial futures contracts
solely for the purpose of hedging its existing portfolio securities or
securities the Series intends to purchase against fluctuations in value caused
by changes in prevailing
    14

       Prudential Municipal Series Fund      Massachusetts Series
             Notes to Financial Statements (Unaudited) Cont'd.

market interest rates. Should interest rates move unexpectedly, the Series may
not achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The use of futures transactions involves the risk of imperfect
correlation in movements in the price of futures contracts, interest rates and
the underlying hedged assets.

      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and original issue
discount paid on purchases of portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.

      Net investment income (other than distribution fees) and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.

      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason no federal income tax provision is
required.

      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends is made monthly. Distributions of
net capital gains, if any, are made annually.

      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.

      Custody Fee Credits:    The Series has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.

Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'). PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation
                                                                          15

of officers of the Fund, occupancy and certain clerical and bookkeeping costs of
the Fund. The Fund bears all other costs and expenses.

      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.

      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'). The Fund compensates PIMS for distributing and
servicing the Fund's Class A, Class B and Class C shares pursuant to plans of
distribution, (the 'Class A, B and C Plans'), regardless of expenses actually
incurred by them. The distribution fees are accrued daily and payable monthly.
No distribution or service fees are paid to PIMS as distributor of the Class Z
shares of the Fund.

      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1% of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the plans were .25 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively.

      PIMS has advised the Series that it has received approximately $300 and
$600 in front-end sales charges resulting from sales of Class A and C shares,
respectively, during the six months ended February 29, 2000. From these fees
PIMS paid such sales charges to affiliated broker-dealers, which in turn paid
commissions to salespersons and incurred other distribution costs.

      PIMS has advised the Series that for the six months ended February 29,
2000, they received approximately $8,100 in contingent deferred sales charges
imposed upon certain redemptions by Class B shareholders.

      PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential
Insurance Company of America ('Prudential').

      The Fund, along with other affiliated registered investment companies (the
'Funds'), entered into a syndicated credit agreement ('SCA') with an
unaffiliated lender. The maximum commitment under the SCA is $1 billion and
interest on any borrowings will be at market rates. For the period
3/11/99-3/9/00, the commitment fee on the unused portion of the credit facility
was .065 of 1%. Subsequent to March 9, 2000, the SCA was renewed with a maximum
commitment of $1 billion at a commitment fee of .080 of 1% of the unused portion
of the credit facility. The expiration date of the SCA is March 9, 2001. The
commitment fee is accrued and paid quarterly on a pro rata basis by the Funds.
Prior to March 11, 1999, the Funds had a credit agreement with a maximum
commitment of $200,000,000. The commitment fee was .055 of 1% on the unused
portion of the credit facility. The Fund did not borrow any amounts during the
six months ended February 29, 2000. The purpose of

the credit agreements is to serve as an alternative source of funding for
capital share redemptions.

Note 3. Other Transactions With Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $7,400 for the services of PMFS.
As of February 29, 2000, approximately $1,200 of such fees were due to PMFS.
Transfer agent fees and expenses in the Statement of Operations include certain
out-of-pocket expenses paid to nonaffiliates.

Note 4. Portfolio Securities
Purchases and sales of investment securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000, were $4,357,933 and
$6,734,646, respectively.

      The United States federal income tax basis of the Fund's investments as of
February 29, 2000 was $35,108,368 and accordingly, net unrealized appreciation
on investments for federal income tax purposes was $787,435 (gross unrealized
appreciation--$1,662,328, gross unrealized depreciation--$874,893).

      The Fund elected, for United States Federal income tax purposes, to treat
capital losses of approximately $54,800 incurred in the ten month period ended
August 31, 1999 as having incurred in the current fiscal year.

      For federal income tax purposes, the Portfolio had a capital loss
carryforward as of August 31, 1999 of approximately $8,200 which expires in
2007. Accordingly, no capital gains distributions are expected to be paid to
shareholders until future net gains have been realized in excess of such
carryforward.

Note 5. Capital
The Series offers Class A, Class B, Class C and Class Z shares. Class A shares
are sold with a front-end sales charge of up to 3%. Class B shares are sold with
a contingent deferred sales charge which declines from 5% to zero depending on
the period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% and a contingent deferred sales charge of 1% during the first
18 months. Class B shares will automatically convert to Class A shares on a
quarterly basis approximately seven years after purchase. A special exchange
privilege is also available for shareholders who qualify to purchase Class A
shares at net asset value. Class Z shares are not subject to any sales or
redemption charge and are offered
                                                                          17

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/Massachusetts
Money Market Series seeks to provide the highest
level of current income that is exempt from
Massachusetts State and federal income taxes,
consistent with liquidity and the preservation of
capital. The Series intends to invest in a
portfolio of short-term municipal debt securities
with maturities of 13 months or less from the state
of Massachusetts, its municipalities, local
governments, and other qualifying issuers (such as
Puerto Rico, Guam, and the U.S. Virgin Islands).
There can be no assurance that the Series will
achieve its investment objective.

Message From the Fund's President   As of April 17, 2000

(PHOTO)
Dear Shareholder
The Federal Reserve increased short-term interest
rates twice to slow U.S. economic growth and fend
off higher inflation during the six months that
ended on February 29, 2000. Prudential's Money
Markets Sector team worked hard to anticipate these
changes in U.S. monetary policy, and acted quickly
to take advantage of good investment opportunities
that emerged as Massachusetts money market yields
rose.

As a result, Prudential Municipal Series
Fund/Massachusetts Money Market Series maintained a
$1.00 net asset value per share, and provided a
competitive yield during its fiscal half year. On
February 29, 2000, the Series' seven-day current
yield was 3.07%, compared with 3.09% for the
average Massachusetts money market fund as tracked
by iMoneyNet, Inc. The
following report takes a closer look at
developments in the municipal money market sector
during the six-month review period, and explains
how the Series was positioned throughout.

New team member brings solid investment expertise
The newest member of Prudential's Money Markets
Sector team is Monica Wong. Prior to joining
Prudential, Monica was a portfolio manager at
Montgomery Asset Management, where she oversaw tax-
exempt assets totaling more than $500 million.
During Monica's 10 years of municipal finance
experience, she also worked as a research analyst,
financial advisor, trader, and underwriter.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

Sector Team Leader) and Monica Wong

Fed tried to curb U.S. economic growth
Shortly before the Series' fiscal half year began
on September 1, 1999, the Federal Reserve increased
the federal funds rate (what U.S. banks charge each
other for overnight loans) by a quarter of a
percentage point to 5.25% from 5.00%. It also
raised the rate at which banks can borrow from the
Federal Reserve system (known as the discount rate)
to 4.75% from 4.50%.

The short-term rate hike rippled through the U.S.
economy, increasing
borrowing costs for consumers and businesses. In
this way, the Fed hoped to rein in the brisk pace
of U.S. economic growth and avert a buildup in
inflationary pressures. Mounting inflation is
particularly hard on people who live on fixed
incomes, because their buying power declines if
their incomes are not adjusted for the rise in
prices.

Reinvesting at higher yields helped the Series
Because we believed that the Fed would continue to
tighten monetary policy, we invested primarily in shorter-term
Massachusetts money market securities from
September 1999 through much of October 1999. As
these securities matured, we planned to reinvest
the money in higher-yielding Massachusetts money
market securities that would likely be available
after any subsequent Fed rate hike.

We did not have to wait long. The U.S. central bank
boosted the federal funds rate to 5.50% and its
discount rate to 5.00% on November 16, 1999. Yields
on Massachusetts money market securities also
climbed, creating attractive buying opportunities.
Among our purchases were bond anticipation notes of
Bedford, Massachusetts, that matured in one year,
and insured general obligation bonds of Ipswich,
Massachusetts, that also matured in one year.

Prudential Municipal Series Fund   Massachusetts Money Market Series
Performance Review

The Ipswich general obligation bonds were a good
alternative to conventional tax-exempt money market
securities because they provided solid yields to
compensate for the fact that they were issued in
moderate-sized blocks. We, like most money
managers, often prefer to buy large blocks of bonds
because they could be easier to sell. However,
owning moderate-sized blocks of insured short-term
municipal bonds that offered higher yields also met
our fundamental buy-and-hold strategy.

Weathering the "January effect"
Our purchases lengthened the Series' weighted
average maturity (WAM), which positioned the Series
longer than the average of comparable funds as
measured by iMoneyNet, Inc. (WAM is a measurement
tool that determines a portfolio's sensitivity to
changes in the level of interest rates. It takes
into account the maturity level of each security
held in a portfolio.)  However, the  Series' WAM
shortened in early January 2000 amid an industry-
wide phenomenon that causes municipal money market
yields to decline.

Known as the "January effect," this period of lower
yields occurred as investors rushed to temporarily
reinvest money received from coupon payments and
maturing bonds in the municipal money market during
the first week of January. Their increased demand
drove yields on municipal money market securities
lower and their prices higher. Because we largely
avoided reinvesting in longer-term municipal money
market securities with yields at such unattractive
levels, the Series' WAM shortened in the new year.

Massachusetts bonds upgraded
Besides the "January effect," the change of year
brought good news for investors in Massachusetts
debt securities. Moody's Investors Service upgraded
the state's general obligation bonds to AA2 from
AA3 on January 13, 2000, even though Massachusetts
residents may vote to cut taxes later in the year.
Moody's noted that the economic strength of
Massachusetts would enable its government to
accommodate a lower tax rate. More than two years
ago, Standard & Poor's also upgraded its rating of
Massachusetts' general obligation bonds to AA-minus
from A-plus.

While Massachusetts received praise for its
economic prowess, the Fed renewed its efforts to
check the powerful U.S. economy. On February 2,
2000, it hiked the federal funds rate to 5.75% and
its discount rate to 5.25%. In the statement
announcing this change in monetary policy, the Fed
warned that further rate hikes might be necessary
to keep the U.S. economy from overheating. February
marked the 107th consecutive month of the economic
expansion, making it the longest in U.S. history.

Looking Ahead
True to its word, the Fed again increased the
federal funds rate to 6.00% and the discount rate
to 5.50% on March 21, 2000. As the U.S. economy
continues to grow rapidly, we believe this will not
be the last time the Fed will take action this
year. With the approach of the tax season, we
intend to again increase the Series' exposure to
very short-term municipal money market securities
in order to accommodate seasonal cash outflows that
usually occur as shareholders pay their income
taxes. Adopting this strategy should position the
Series to lock in higher yields that become
available as the supply of municipal money market
securities balloons during the tax season.

       Prudential Municipal Series Fund      Massachusetts Money Market Series
             Notes to Financial Statements (Unaudited)
      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of
eleven series. The monies of each series are invested in separate, independently
managed portfolios. The Massachusetts Money Market Series (the 'Series')
commenced investment operations on August 5, 1991. The Series is nondiversified
and seeks to provide the highest level of income that is exempt from
Massachusetts State and federal income taxes with minimum risk by investing in
'investment grade' tax-exempt securities having a maturity of 13 months or less
and whose ratings are within the 2 highest ratings categories by a nationally
recognized statistical rating organization, or if not rated, are of comparable
quality. The ability of the issuers of the securities held by the Series to meet
their obligations may be affected by economic developments in a specific state,
industry or region.
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.
      Securities Valuations:    Portfolio securities of the Series are valued at
amortized cost, which approximates market value. The amortized cost method of
valuation involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of any discount or
premium.
      All securities are valued as of 4:30 p.m., New York time.
      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of investments are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and accretes
original issue discount on portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.
      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason, no federal income tax provision is
required.
      Dividends:    The Series declares all of its net investment income and net
realized short-term capital gains or losses, if any, as dividends daily to its
shareholders of record at the time of such declaration. Payment of dividends is
made monthly. Income distributions and capital gain distributions are determined
in accordance with
    12

       Prudential Municipal Series Fund      Massachusetts Money Market Series
             Notes to Financial Statements (Unaudited) Cont'd.
income tax regulations which may differ from generally accepted accounting
principles.
      Custody Fee Credits:    The Fund has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation of officers of the Fund, occupancy and certain clerical
and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.
      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.
      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Fund. The
Fund compensates PIMS for distributing and servicing the Fund's shares pursuant
to the plans of distribution regardless of expenses actually incurred by PIMS.
The Series reimbursed PIMS for distributing and servicing the Fund's shares
pursuant to the plan of distribution at an annual rate of .125 of 1% of the
Series' average daily net assets. The distribution fees are accrued daily and
payable monthly.
      PIMS, PIFM and PIC are indirect wholly owned subsidiaries of The
Prudential Insurance Company of America.
Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $6,800 for the services of PMFS.
As of February 29, 2000, approximately $1,200 of such fees were due to PMFS.
Transfer agent fees and expenses in the Statement of Operations include certain
out-of-pocket expenses paid to nonaffiliates.
                                                                          13

Prudential Municipal Series Fund   Massachusetts Money Market Series
Getting the Most From Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read
this--they don't read annual and semiannual reports.
It's quite understandable. These annual and
semiannual reports are prepared to comply with
federal regulations, and are often written in
language that is difficult to understand. So when
most people run into those particularly daunting
sections of these reports, they don't read them.
We think that's a mistake
At Prudential Mutual Funds, we've made some changes
to our report to make it easier to understand and
more pleasant to read. We hope you'll find it
profitable to spend a few minutes familiarizing
yourself with your investment. Here's what you'll
find in the report:

Performance at a Glance
Since an investment's performance is often a
shareholder's primary concern, we present
performance information in two different formats.
You'll find it first on the "Performance at a
Glance" page where we compare the Fund and the
comparable average calculated by Lipper, Inc., a
nationally recognized mutual fund rating agency. We
report both the cumulative total returns and the
average annual total returns. The cumulative total
return is the total amount of income and
appreciation the Fund has achieved in various time
periods. The average annual total return is an
annualized representation of the Fund's
performance. It gives you an idea of how much the
Fund has earned in an average year for a given time
period. Under the performance box, you'll see
legends that explain the performance information,
whether fees and sales charges have been included
in returns, and the inception dates for the Fund's
share classes.

See the performance comparison charts at the back
of the report for more performance information.
Please keep in mind that past performance is not
indicative of future results.

Performance review

The portfolio manager, who invests your money for
you, reports on
successful--and not-so-successful--strategies in this
section of your report. Look for recent purchases
and sales here, as well as information about the
sectors the portfolio manager favors, and any
changes that are on the
drawing board.
Portfolio of Investments
This is where the report begins to appear
technical, but it's really just a
listing of each security held at the end of the
reporting period, along with valuations and other
information. Please note that sometimes we discuss
a security in the Performance Review that doesn't
appear in this listing because it was sold before
the close of the reporting period.
Statement of Assets and Liabilities
The balance sheet shows the assets (the value of
the Fund's holdings),
liabilities (how much the Fund owes), and net
assets (the Fund's equity, or holdings after the
Fund pays its debts) as of the end of the reporting
period. It also shows how we calculate the net
asset value per share for each class of shares. The
net asset value is reduced by payment of your
dividend, capital gain, or other distribution, but remember
that the money or new shares are being paid or
issued to you. The net asset value fluctuates
daily, along with the value of every security in
the portfolio.
Statement of Operations
This is the income statement, which details income
(mostly interest and
dividends earned) and expenses (including what you
pay us to manage your money). You'll also see
capital gains here--both realized and unrealized.

<PAGE>

Prudential Municipal Series Fund   Massachusetts Money Market Series
Getting the Most From Your Prudential Mutual Fund

Statement of Changes in Net Assets
This schedule shows how income and expenses
translate into changes
in net assets. The Fund is required to pay out the
bulk of its income to shareholders every year, and
this statement shows you how we do it (through
dividends and distributions) and how that affects
the net assets. This statement also shows how money
from investors flowed into and out of the Fund.
Notes to Financial Statements
This is the kind of technical material that can
intimidate readers, but it does contain useful
information. The Notes provide a brief history and
explanation of your Fund's objectives. In addition,
they outline how Prudential Mutual Funds prices
securities. The Notes also explain who manages and
distributes the Fund's shares and, more
importantly, how much they are paid for doing so.
Finally, the Notes explain how many shares are
outstanding and the number issued and redeemed over
the period.
Financial Highlights
This information contains many elements from prior
pages, but on a per-share basis. It is designed to
help you understand how the Fund performed, and to
compare this year's performance and expenses to
those of prior years.
Independent Auditor's Report
Once a year, an outside auditor looks over our
books and certifies that the information is fairly
presented and complies with generally accepted
accounting principles.
Tax Information
This is information that we report annually about
how much of your total return is taxable. Should
you have any questions, you may want to consult a
tax adviser.

<PAGE>

www.prudential.com  (800) 225-1852

Performance Comparison
These charts are included in the annual report and
are required by the Securities Exchange Commission.
Performance is presented here as a hypothetical
$10,000 investment in the Fund since its inception
or for 10 years (whichever is shorter). To help you
put that return in context, we
are required to include the performance of an
unmanaged, broad-based securities index as well.
The index does not reflect the cost of buying the
securities it contains or the cost of managing a
mutual fund. Of course, the index holdings do not
mirror those of the Fund--the index is a broad-based
reference point commonly used by investors to
measure how well they are doing. A definition of
the selected index is also provided. Investors
cannot invest directly in an index.

Prudential Municipal Series Fund   Massachusetts Money Market Series
Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!
Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.
Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/New Jersey Series'
investment objective is to maximize current income
that is exempt from New Jersey State and federal
income taxes, consistent with the preservation of
capital. However, certain shareholders may be
subject to the federal alternative minimum tax
(AMT) because some of the Series' bonds are AMT
eligible. There can be no assurance the Series will
achieve its investment objective.

benchmark Lipper Average was a negative 1.70%.
After the initial sales charge, the Class A shares'
return was a negative 3.90%. Prices of municipal
bonds declined primarily because investors required
higher yields in light of two short-term rate
increases implemented by the Federal Reserve during
our review period to slow the rapid pace of U.S.
economic growth.

Staying the course amid ups and downs of financial
markets
Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld

Performance Review

Bonds Sector Team Leader) and Scott Diamond

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest
rates by the Federal Reserve and sales of municipal
bonds by investors who wanted to realize tax losses
pressured the prices of tax-exempt debt securities.
Given this bearish trend, we positioned the Series
so that it would be less vulnerable to the decline
in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also
engineered two quarter-point increases that raised
its discount rate on loans to banks from the
Federal Reserve system to 5.25% by February 2000.
As short-term rates rose, investors required higher
yields on both short- and long-term municipal
bonds, which caused their prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvest in new bonds or other bond funds
with a lower cost basis for tax purposes (due to
the higher level of yields). This is called "tax
loss swapping". In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

Prudential Municipal Series Fund   New Jersey Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase the Series'
distribution yield in this rising-interest-rate
environment. An increased exposure to the
transportation sector, industrial development
bonds, and others benefited the Series' yield.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally provides some degree of
protection by making the portfolio less sensitive
to the rise in bond yields. (Duration measures how
much a portfolio's bonds will fluctuate in price
for a given change in interest rates. It is
expressed in years.) The Series' share classes,
without sales charges factored in, performed better
than its benchmark Lipper Average, which does not
consider sales charges. This occurred largely
because we kept the Series' duration shorter than
average for most of its fiscal half year.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for
investors who might want to buy them. Here's how it
works: When yields climb beyond a certain point for
every municipal bond, the market discount on that
bond may become subject to ordinary income taxes
for new buyers.

This lowers the value of the bond because new
buyers would want to purchase the bond cheaply
enough to compensate for the greater tax liability.

Looking Ahead
Shortly after our six-month review period ended,
the Fed engineered another quarter-point rate hike
that raised its target for the federal funds rate
to 6.00% and its discount rate to 5.50%. We believe
the Fed's efforts to tighten monetary policy will
slow the U.S. economic expansion in 2000 from its
7.30% annual pace in the fourth quarter of 1999.
Moderating economic growth could help bolster the
performance of municipal bonds, but detract from
the performance of equities.

Meanwhile, the powerful U.S. economic expansion has
improved the credit quality of many state and local
governments and reduced their borrowing needs,
allowing them to issue fewer bonds. The supply of
new municipal bonds has also fallen because the
rising-interest-rate environment provided less
opportunity for issuers to save money by replacing
older higher coupon bonds with new lower-coupon
bonds. With the declining supply, if investor
demand remains strong, the tax-exempt bond market
should perform better than other U.S. fixed-income
markets in 2000.

       Prudential Municipal Series Fund      New Jersey Series
             Notes to Financial Statements (Unaudited)
      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end management investment company.
The Fund was organized as a Massachusetts business trust on May 18, 1984, and
consists of 11 series. The monies of each series are invested in separate,
independently managed portfolios. The New Jersey Series (the 'Series') commenced
investment operations in March 1988. The Series is diversified and seeks to
achieve its investment objective of obtaining the maximum amount of income
exempt from federal and applicable state income taxes with the minimum of risk
by investing in 'investment grade' tax-exempt securities whose ratings are
within the four highest ratings categories by a nationally recognized
statistical rating organization or, if not rated, are of comparable quality. The
ability of the issuers of the securities held by the Series to meet their
obligations may be affected by economic or political developments in a specific
state, industry or region.
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.
      Securities Valuations: The Fund values municipal securities (including
commitments to purchase such securities on a 'when-issued' basis) on the basis
of prices provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing service, a security is valued at its fair value as determined under
procedures established by the Trustees.
      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost which approximates market value.
      All securities are valued as of 4:15 p.m., New York time.
      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and original issue
discount paid on purchases of portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.
      Net investment income (other than distribution fees) and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.

       Prudential Municipal Series Fund      New Jersey Series
             Notes to Financial Statements (Unaudited) Cont'd.
      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason no federal income tax provision is
required.
      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends is made monthly. Distributions of
net capital gains, if any, are made annually.
      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'). PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation of officers of the Fund, occupancy and certain clerical
and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.
      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.
      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS') which acts as distributor of the Class A, Class
B, Class C and Class Z shares of the Fund. The Fund compensates PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares
pursuant to plans of distribution, (the 'Class A, B and C Plans'), regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly. No distribution or service fees are paid to PIMS as distributor
of the Class Z shares of the Fund.
      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50% of 1%
and 1% of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plans were .25 of 1%, .50 of 1% and .75 of
1% of the average
                                                                          17

daily net assets of the Class A, B and C shares, respectively, for the six
months ended February 29, 2000.
      PIMS advised the Series that it has received approximately $6,000 and
$4,600 in front-end sales charges resulting from sales of Class A and Class C
shares, respectively, during the six months ended February 29, 2000. From these
fees, PIMS paid such sales charges to affiliated broker-dealers, which in turn
paid commissions to salespersons and incurred other distribution costs.
      PIMS has advised the Series that during the six months ended February 29,
2000, it received approximately $40,900 and $300 in contingent deferred sales
charges imposed upon certain redemptions by Class B and Class C shareholders,
respectively.
      PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential
Insurance Company of America.
      The Series, along with other affiliated registered investment companies
(the 'Funds'), entered into a syndicated credit agreement ('SCA') with an
unaffiliated lender. The maximum commitment under the SCA is $1 billion and
interest on any borrowings will be at market rates. For the period
3/11/99-3/9/00, the commitment fee on the unused portion of the credit facility
was .065 of 1%. Subsequent to March 9, 2000, the SCA was renewed with a maximum
commitment of $1 billion at a commitment fee of .080 of 1% of the unused portion
of the credit facility. The expiration date of the SCA is March 9, 2001. The
commitment fee is accrued and paid quarterly on a pro rata basis by the Funds.
Prior to March 11, 1999, the Funds had a credit agreement with a maximum
commitment of $200,000,000. The commitment fee was .055 of 1% on the unused
portion of the credit facility. The Fund did not borrow any amounts during the
six months ended February 29, 2000. The purpose of the credit agreements is to
serve as an alternative source of funding for capital share redemptions.
Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $33,400 for the services of
PMFS. As of February 29, 2000, approximately $5,400 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations include
certain out-of-pocket expenses paid to nonaffiliates.

Note 4. Portfolio Securities
Purchases and sales of portfolio securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000, were $18,225,694 and
$32,038,392, respectively.
      The cost basis of investments for federal income tax purposes at February
29, 2000 was substantially the same as for financial reporting purposes and
accordingly, net unrealized depreciation of investments for federal income tax
purposes was $922,798 (gross unrealized appreciation--$4,333,217; gross
unrealized depreciation--$5,256,015).
Note 5. Capital
The Series offers Class A, Class B, Class C and Class Z shares. Class A shares
are sold with a front-end sales charge of up to 3%. Class B shares are sold with
a contingent deferred sales charge which declines from 5% to zero depending on
the period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% and a contingent deferred sales charge of 1% during the first
18 months. Class B shares will automatically convert to Class A shares on a
quarterly basis approximately seven years after purchase. A special exchange
privilege is also available for shareholders who qualify to purchase Class A
shares at net asset value. Class Z shares are not subject to any sales or
redemption charge and are offered exclusively for sale to a limited group of
investors.
      The Fund has authorized an unlimited number of shares of beneficial
interest of each class at $.01 par value per share.
      Transactions in shares of beneficial interest were as follows:

Prudential Municipal Series Fund   New Jersey Series
Getting the Most From Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read
this--they don't read annual and semiannual reports.
It's quite understandable. These annual and
semiannual reports are prepared to comply with
federal regulations, and are often written in
language that is difficult to understand. So when
most people run into those particularly daunting
sections of these reports, they don't read them.

We think that's a mistake
At Prudential Mutual Funds, we've made some changes
to our report to make it easier to understand and
more pleasant to read. We hope you'll find it
profitable to spend a few minutes familiarizing
yourself with your investment. Here's what you'll
find in the report:

Performance at a Glance
Since an investment's performance is often a
shareholder's primary concern, we present
performance information in two different formats.
You'll find it first on the "Performance at a
Glance" page where we compare the Fund and the
comparable average calculated by Lipper, Inc., a
nationally recognized mutual fund rating agency. We
report both the cumulative total returns and the
average annual total returns. The cumulative total
return is the total amount of income and
appreciation the Fund has achieved in various time
periods. The average annual total return is an
annualized representation of the Fund's
performance. It gives you an idea of how much the
Fund has earned in an average year for a given time
period. Under the performance box, you'll see
legends that explain the performance information,
whether fees and sales charges have been included
in returns, and the inception dates for the Fund's
share classes.

See the performance comparison charts at the back
of the report for more performance information.
Please keep in mind that past performance is not
indicative of future results.

www.prudential.com                (800) 225-1852
Performance review

The portfolio manager, who invests your money for
you, reports on
successful--and not-so-successful--strategies in this
section of your report. Look for recent purchases
and sales here, as well as information about the
sectors the portfolio manager favors, and any
changes that are on the drawing board.

Portfolio of Investments
This is where the report begins to appear
technical, but it's really just a
listing of each security held at the end of the
reporting period, along with valuations and other
information. Please note that sometimes we discuss
a security in the Performance Review that doesn't
appear in this listing because it was sold before
the close of the reporting period.

Statement of Assets and Liabilities
The balance sheet shows the assets (the value of
the Fund's holdings),
liabilities (how much the Fund owes), and net
assets (the Fund's
equity, or holdings after the Fund pays its debts)
as of the end of the reporting period. It also
shows how we calculate the net asset value per
share for each class of shares. The net asset value
is reduced by payment of your
dividend, capital gain, or other distribution, but
remember that the money or new shares are being
paid or issued to you. The net asset value
fluctuates daily, along with the value of every
security in the portfolio.

Statement of Operations
This is the income statement, which details income
(mostly interest and
dividends earned) and expenses (including what you
pay us to manage your money). You'll also see
capital gains here--both realized and unrealized.

<PAGE>

Prudential Municipal Series Fund   New Jersey Series
Getting the Most From Your Prudential Mutual Fund

Statement of Changes in Net Assets
This schedule shows how income and expenses
translate into changes
in net assets. The Fund is required to pay out the
bulk of its income to shareholders every year, and
this statement shows you how we do it (through
dividends and distributions) and how that affects
the net assets. This statement also shows how money
from investors flowed into and out of the Fund.

Notes to Financial Statements
This is the kind of technical material that can
intimidate readers, but it does contain useful
information. The Notes provide a brief history and
explanation of your Fund's objectives. In addition,
they outline how Prudential Mutual Funds prices
securities. The Notes also explain who manages and
distributes the Fund's shares and, more
importantly, how much they are paid for doing so.
Finally, the Notes explain how many shares are
outstanding and the number issued and redeemed over
the period.

Financial Highlights
This information contains many elements from prior
pages, but on a
per-share basis. It is designed to help you
understand how the Fund
performed, and to compare this year's performance
and expenses to those of prior years.

Independent Auditor's Report
Once a year, an outside auditor looks over our
books and certifies that the information is fairly
presented and complies with generally accepted
accounting principles.

Tax Information
This is information that we report annually about
how much of your total return is taxable. Should
you have any questions, you may want to consult a
tax adviser.

<PAGE>

www.prudential.com  (800) 225-1852
Performance Comparis
on
These charts are included in the annual report and
are required by the Securities Exchange Commission.
Performance is presented here as a hypothetical
$10,000 investment in the Fund since its inception
or for 10 years (whichever is shorter). To help you
put that return in context, we
are required to include the performance of an
unmanaged, broad-based securities index as well.
The index does not reflect the cost of buying the
securities it contains or the cost of managing a
mutual fund. Of course, the index holdings do not
mirror those of the Fund--the index is a broad-based
reference point commonly used by investors to
measure how well they are doing. A definition of
the selected index is also provided. Investors
cannot invest directly in an index.

Prudential Municipal Series Fund   New Jersey Series
Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/New Jersey Money
Market Series seeks to provide the highest level of
current income that is exempt from New Jersey State
and federal income taxes, consistent with liquidity
and the preservation of capital. The Series intends
to invest in a portfolio of short-term municipal
debt securities with maturities of 13 months or
less from the state of New Jersey, its
municipalities, local governments, and other
qualifying issuers (such as Puerto Rico, Guam, and
the U.S. Virgin Islands). There can be no assurance
that the Series will achieve its investment
objective.

Message From the Fund's President   As of April 17, 2000


Dear Shareholder
The Federal Reserve increased short-term interest
rates twice to slow U.S. economic growth and fend
off higher inflation during the six months that
ended on February 29, 2000. Prudential's Money
Markets Sector team worked hard to anticipate these
changes in U.S. monetary policy, and acted quickly
to take advantage of good investment opportunities.

As a result, Prudential Municipal Series Fund/New
Jersey Money Market Series maintained a $1.00 net
asset value per share, and provided a competitive
yield. On February 29, 2000, the Series' seven-day
current yield was 3.08%, compared with 3.05% for
the average New Jersey money market fund as tracked
by iMoneyNet, Inc. The following report takes a
closer look at developments in the municipal money
market sector during the six-month review period,
and explains how the Series was positioned
throughout.

High-quality investments can help reduce risk
Having a conservative, high-quality investment
alternative, such as a money market fund, made good
sense for investors who were concerned about
volatile conditions in the financial markets.
Indeed, investors may do well to consider investing
in a money market fund as part of their overall
investment strategy. For any of life's unexpected
events, it is reassuring to have quick access to
your money and an investment vehicle that
emphasizes safety of principal and liquidity.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

Team Leader) and Richard S. Lynes

Fed tried to curb U.S. economic growth
Shortly before the Series' fiscal half year began
on September 1, 1999, the Federal Reserve increased
the federal funds rate (what U.S. banks charge each
other for overnight loans) by a quarter of a
percentage point to 5.25% from 5.00%. It also
raised the rate at which banks can borrow from the
Federal Reserve system (known as the discount rate)
to 4.75% from 4.50%.

The short-term rate hike rippled through the U.S.
economy, increasing borrowing costs for consumers
and businesses. In this way, the Fed hoped to rein
in the brisk pace of U.S. economic growth and avert
a buildup in inflationary pressures. Mounting
inflation is particularly hard on people who live
on fixed incomes, because their buying power
declines if their incomes are not adjusted for the
rise in prices.

Series locked in solid yields
When the Fed tightens U.S. monetary policy, yields
in the municipal money market climb, but at a lag
to the rise in taxable money market yields.
However, the impact of the Fed-engineered rate hike
was muted by the strong investor demand for New
Jersey money market securities. Therefore, we
believe our decision to buy longer-term New Jersey
money market securities in September 1999 and early
October 1999, which was long before the Fed's
subsequent rate increase in November 1999, was
strategically sound.

Among our purchases were bond anticipation notes of
Morris Township. In addition, we bought one-year
bonds of Jersey City that were rated Aaa because
their interest and principal payments are insured
by a municipal bond insurance company. The Jersey
City bonds also provided an attractive

Series' weighted average maturity (WAM), which
positioned the Series longer than the average of
comparable funds as measured by iMoneyNet, Inc.
(WAM is a measurement tool that determines a
portfolio's sensitivity to changes in the level of
interest rates. It takes into account the maturity
level of each security held in a portfolio.)
Lengthening the Series' WAM by purchasing
attractively priced securities enhanced its yield.

Fed repeatedly applied the brakes
The Fed's next move occurred on November 16, 1999.
It increased the federal funds rate to 5.50% and
its discount rate to 5.00%. The pace of U.S.
economic growth, however, accelerated in the final
three months of 1999. Not surprisingly, the Fed
renewed its efforts to cool off the economy in the
new year. It raised the federal funds rate to 5.75%
and its discount rate to 5.25% on February 2, 2000.

New year brought good buying opportunities
Following the February short-term rate increase,
many good buying opportunities emerged in New
Jersey money market securities. Among our purchases
were "prerefunded" bonds maturing in July 2000 that
are backed by direct obligations of the U.S.
government. We also purchased one-year bonds of the
New Jersey Sports and Exposition Authority that
were rated Aa3 by Moody's Investors Service and
were recently upgraded by Standard & Poor's to AA-
minus. These purchases again helped to extend the
Series' WAM and bolster its yield.

Looking Ahead
On March 21, 2000, the Fed again increased the
federal funds rate to 6.00% and the discount rate
to 5.50%. As the economy continues to grow rapidly,
we believe this will not be the last time the Fed
will take action this year.

With the approach of the tax season, we intend to
again increase the Series' exposure to very short-
term municipal money market securities in order to
accommodate seasonal cash outflows that usually
occur as shareholders pay their income taxes.
Adopting this strategy should position the Series
to lock in higher yields that become available as
the supply of municipal money market securities
balloons during the tax season.

       Prudential Municipal Series Fund      New Jersery Money Market Series
             Notes to Financial Statements (Unaudited)

      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940 as an open-end management investment company. The
Fund was organized as a Massachusetts business trust on May 18, 1984 and
consists of 13 series. The monies of each series are invested in separate,
independently managed portfolios. The New Jersey Money Market Series (the
'Series') commenced investment operations on December 3, 1990. The Series is
nondiversified and seeks to achieve its investment objective of providing the
highest level of income that is exempt from New Jersey state and federal income
taxes with a minimum of risk by investing in 'investment grade' tax-exempt
securities maturing within 13 months or less and whose ratings are within the
two highest ratings categories by a nationally recognized statistical rating
organization, or if not rated, are of comparable quality. The ability of the
issuers of the securities held by the Series to meet their obligations may be
affected by economic developments in a specific state, industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.

      Securities Valuations:    Portfolio securities of the Series are valued at
amortized cost, which approximates market value. The amortized cost method of
valuation involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of any discount or
premium.

      All securities are valued as of 4:30 p.m., New York time.

      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of investments are calculated on the identified cost basis. The Series amortizes
premiums and accretes original issue discount on portfolio securities as
adjustments to interest income. Interest income is recorded on the accrual
basis. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.

      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason, no federal income tax provision is
required.

      Dividends:    The Series declares daily dividends from net investment
income. Payment of dividends is made monthly.

      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.

             Notes to Financial Statements (Unaudited) Cont'd.

      Custody Fee Credits:    The Fund has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.

Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation of officers of the Fund, occupancy and certain clerical
and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

      The management fee paid to PIFM is computed daily and payable monthly, at
an annual rate of .50 of 1% of the average daily net assets of the Series.

      The Series has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS') which acts as the distributor of the Series
shares. The Series compensates PIMS for distributing and servicing the Series'
shares pursuant to the plan of distribution at an annual rate of .125 of 1% of
the Series' average daily net assets. The distribution fee is accrued daily and
payable monthly.

      PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential
Insurance Company of America ('Prudential').

Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $27,000 for the services of
PMFS. As of February 29, 2000, approximately $4,400 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations include
certain out-of-pocket expenses paid to nonaffiliates.
                                                                          15

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/New York Series'
investment objective is to maximize current income
that is exempt from New York State, New York City,
and federal income taxes, consistent with the
preservation of
capital. However, certain shareholders may be
subject to the federal alternative minimum tax
(AMT) because some of the Series' bonds are AMT
eligible. There can be no assurance the Series will
achieve its investment objective.

Message From the Fund's President    As of April 17, 2000

(PHOTO)
Dear Shareholder
The Class A shares of Prudential Municipal Series
Fund/New York Series had a negative return of 0.57%
during its fiscal half year that ended February 29,
2000. For the same period, the return on the
Series' benchmark Lipper Average was a negative
1.27%. After the initial sales charge, the Class A
shares' return was a negative 3.55%. Prices of
municipal bonds declined primarily because
investors required higher yields in light of two
short-term rate increases implemented by the
Federal Reserve during our review period to slow
the rapid pace of U.S. economic growth.

Staying the course amid ups and downs of financial
markets
Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in
Prudential mutual funds.
Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest
rates by the Federal Reserve and sales of municipal
bonds by investors who wanted to realize tax losses
pressured the prices of tax-exempt debt securities.
Given this bearish trend, we positioned the Series
so that it would be less vulnerable to the decline
in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also engineered two quarter-point increases
that raised its discount rate on loans
to banks from the Federal Reserve system to 5.25%
by February 2000. As
short-term rates rose, investors required higher
yields on both short- and long-term municipal
bonds, which caused their prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvested in new bonds or other bond
funds with a lower cost basis for tax purposes (due
to the higher level of yields). This is called "tax
loss swapping." In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

automatically convert to Class A shares, on a
quarterly basis, approximately seven years after

Z shares are not subject to a sales charge or
distribution and service (12b-1) fees. Without

Prudential Municipal Series Fund    New York Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase its distribution
yield in this rising interest-rate environment.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally provides some degree of
protection by making the portfolio less sensitive
to the rise in bond yields. (Duration measures how
much a portfolio's bonds will fluctuate in price
for a given change in interest rates. It is
expressed in years.) The Series' share classes,
without sales charges factored in, performed better
than its benchmark Lipper Average, which does not
consider sales charges. This occurred largely
because we kept its duration shorter than average
for most of its fiscal half year.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for
investors who might want to buy them. Here's how it
works: When yields climb beyond a certain point for
every municipal bond, the market discount on that
bond may become subject to ordinary income taxes
for new buyers.

This lowers the value of the bond because new
buyers would want to purchase the bond cheaply
enough to compensate for the greater tax
liability.

New York State bonds upgraded
Standard & Poor's (S&P) upgraded its ratings of New
York State's general obligation bonds to A-plus
from single-A and all other state appropriation
debt to A-minus from BBB-plus in November 1999. (In
March 2000, S&P upgraded its rating of state
appropriation debt to single-A from A-minus.)
Standard & Poor's praised the state's slow, but
steady economic growth; fundamental changes in its
fiscal discipline and management; and marginal
success in reducing pace of borrowing. As of
February 29, 2000, the Series held 8.45% of its
total investments in state appropriation debt.

Looking Ahead
Shortly after our six-month review period ended,
the Fed engineered another quarter-point rate hike
that raised its target for the federal funds rate
to 6.00% and its discount rate to 5.50%. We believe
the Fed's efforts to tighten monetary policy will
slow the U.S. economic expansion in 2000 from its
7.30% annual pace in the fourth quarter of 1999.
Moderating economic growth could help bolster the
performance of municipal bonds, but detract from
the performance of equities.

Meanwhile, the powerful U.S.
economic expansion has improved the credit quality
of many state and local governments and reduced
their borrowing needs, allowing them to issue fewer
bonds. The supply of new municipal bonds has also
decreased because the rising-interest-rate
environment provided less opportunity for issuers
to save money by replacing older higher-coupon
bonds with new lower-coupon bonds. With the
declining supply, if investor demand remains
strong, the tax-exempt bond market should perform
better than other U.S. fixed-income markets in
2000.

       Prudential Municipal Series Fund      New York Series
             Notes to Financial Statements (Unaudited)

      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940 as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of 11
series. The monies of each series are invested in separate, independently
managed portfolios. The New York Series (the 'Series') commenced investment
operations in September 1984. The Series is diversified and its investment
objective is to maximize current income that is exempt from New York State, New
York City and federal income taxes consistent with the preservation of capital,
and in conjunction therewith, the Series may invest in debt securities with the
potential for capital gain. The Series seeks to achieve the objective by
investing primarily in New York State, municipal and local government
obligations and obligations of other qualifying issuers. The ability of the
issuers of the securities held by the Series to meet their obligations may be
affected by economic developments in a specific state, industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.

      Securities Valuations:    The Series values municipal securities
(including commitments to purchase such securities on a 'when-issued' basis) on
the basis of prices provided by a pricing service which uses information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining values. If market quotations are not readily available
from such pricing service, a security is valued at its fair value as determined
under procedures established by the Trustees.

      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost.

      All securities are valued as of 4:15 p.m., New York time.

      Financial Futures Contracts:    A financial futures contract is an
agreement to purchase (long) or sell (short) an agreed amount of securities at a
set price for delivery on a future date. Upon entering into a financial futures
contract, the Series is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Series each day, depending on
the daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
    16

             Notes to Financial Statements (Unaudited) Cont'd.

loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

      The Series invests in financial futures contracts in order to hedge its
existing portfolio securities or securities the Series intends to purchase,
against fluctuations in value caused by changes in prevailing interest rates.
Should interest rates move unexpectedly, the Series may not achieve the
anticipated benefits of the financial futures contracts and may realize a loss.
The use of futures transactions involves the risk of imperfect correlation in
movements in the price of futures contracts, interest rates and the underlying
hedged assets.

      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and accretes
original issue discount paid on purchases of portfolio securities as adjustments
to interest income. Expenses are recorded on the accrual basis which may require
the use of certain estimates by management.

      Net investment income (other than distribution fees), and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.

      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason, no federal income tax provision is
required.

      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends is made monthly. Distributions of
net capital gains, if any, are made annually.

      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.

      Custody Fee Credits:    The Fund has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.
                                                                          17

Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation of officers of the Fund, occupancy and certain clerical
and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.

      The Fund has a distribution agreement with Prudential Investment
Management Services ('PIMS'), which acts as the distributor of the Class A,
Class B, Class C and Class Z shares of the Fund. The Fund compensates PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares,
pursuant to a plan of distribution, (the 'Class A, B and C Plans'), regardless
of expenses actually incurred by them. The distribution fees are accrued daily
and payable monthly. No distribution or service fees are paid to PIMS as
distributor of the Class Z shares of the Fund.

      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1% of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plans were .25 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively,
for the six months ended February 29, 2000.

      PIMS has advised the Series that it received approximately $3,500 and
$1,600 in front-end sales charges resulting from sales of Class A and Class C
shares, respectively during the six months ended February 29, 2000. From these
fees, PIMS paid such sales charges to affiliated broker-dealers, which in turn
paid commissions to salespersons and incurred other distribution costs.

      PIMS has advised the Series that for the six months ended February 29,
2000, it received approximately $46,400 and $300 in contingent deferred sales
charges imposed upon certain redemptions by Class B and C shareholders,
respectively.

      PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential
Insurance Company of America.

      The Fund, along with other affiliated registered investment companies (the
'Funds'), entered into a syndicated credit agreement ('SCA') with an
unaffiliated lender. The maximum commitment under the SCA is $1 billion and
interest on any
    18

borrowings will be at market rates. For the period 3/11/99-3/9/00, the
commitment fee on the unused portion of the credit facility was .065 of 1%.
Subsequent to March 9, 2000, the SCA was renewed with a maximum commitment of $1
billion at a commitment fee of .080 of 1% of the unused portion of the credit
facility. The expiration date of the SCA is March 9, 2001. The commitment fee is
accrued and paid quarterly on a pro rata basis by the Funds. Prior to March 11,
1999, the Funds had a credit agreement with a maximum commitment of
$200,000,000. The commitment fee was .055 of 1% on the unused portion of the
credit facility. The Fund did not borrow any amounts during the six months ended
February 29, 2000. The purpose of the credit agreements is to serve as an
alternative source of funding for capital share redemptions.

Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $45,200 for the services of
PMFS. As of February 29, 2000, approximately $7,400 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations include
certain out-of-pocket expenses paid to nonaffiliates.

Note 4. Portfolio Securities
Purchases and sales of portfolio securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000 were $31,343,985 and
$42,858,788, respectively.

      The cost basis of investments for federal income tax purposes at February
29, 2000 was substantially the same as for financial reporting purposes and
accordingly, net unrealized appreciation on investments for federal income tax
purposes was $2,060,900 (gross unrealized appreciation--$6,921,733, gross
unrealized depreciation--$4,860,833).

      In addition for federal income tax purposes, the Series elected to treat
net realized capital losses of approximately $270,918 incurred in the ten month
period ended August 31, 1999 as having occurred in the current fiscal year.

Note 5. Capital
The Series offers Class A, Class B, Class C and Class Z shares. Class A shares
are sold with a front-end sales charge of up to 3%. Class B shares are sold with
a contingent deferred sales charge which declines from 5% to zero depending on
the period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% and a contingent deferred sales charge of 1% during the first

months. Class B shares automatically convert to Class A shares on a quarterly
basis approximately seven years after purchase. A special exchange privilege is
also available for shareholders who qualify to purchase Class A shares at net
asset value. Class Z shares are not subject to any sales or redemption charge
and are offered exclusively for sale to a limited group of investors.

      The Fund has authorized an unlimited number of shares of beneficial
interest of each class at $.01 par value per share.

      Transactions in shares of beneficial interest were as follows:

Prudential Municipal Series Fund    New York Series
Getting the Most From Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read
this--they don't read annual and semiannual reports.
It's quite understandable. These annual and
semiannual reports are prepared to comply with
federal regulations, and are often written in
language that is difficult to understand. So when
most people run into those particularly daunting
sections of these reports, they don't read them.

We think that's a mistake
At Prudential Mutual Funds, we've made some changes
to our report to make it easier to understand and
more pleasant to read. We hope you'll find it
profitable to spend a few minutes familiarizing
yourself with your investment. Here's what you'll
find in the report:

Performance at a Glance
Since an investment's performance is often a
shareholder's primary concern, we present
performance information in two different formats.
You'll find it first on the "Performance at a
Glance" page where we compare the Fund and the
comparable average calculated by Lipper, Inc., a
nationally recognized mutual fund rating agency. We
report both the cumulative total returns and the
average annual total returns. The cumulative total
return is the total amount of income and
appreciation the Fund has achieved in various time
periods. The average annual total return is an
annualized representation of the Fund's
performance. It gives you an idea of how much the
Fund has earned in an average year for a given time
period. Under the performance box, you'll see
legends that explain the performance information,
whether fees and sales charges have been included
in returns, and the inception dates for the Fund's
share classes.

See the performance comparison charts at the back
of the report for more performance information.
Please keep in mind that past performance is not
indicative of future results.

www.prudential.com                     (800) 225-1852

Performance review
The portfolio manager, who invests your money for
you, reports on
successful--and not-so-successful--strategies in this
section of your report. Look for recent purchases
and sales here, as well as information about the
sectors the portfolio manager favors, and any
changes that are on the drawing board.

Portfolio of Investments
This is where the report begins to appear
technical, but it's really just a
listing of each security held at the end of the
reporting period, along with valuations and other
information. Please note that sometimes we discuss
a security in the Performance Review that doesn't
appear in this listing because it was sold before
the close of the reporting period.

Statement of Assets and Liabilities
The balance sheet shows the assets (the value of
the Fund's holdings),
liabilities (how much the Fund owes), and net
assets (the Fund's
equity, or holdings after the Fund pays its debts)
as of the end of the reporting period. It also
shows how we calculate the net asset value per
share for each class of shares. The net asset value
is reduced by payment of your
dividend, capital gain, or other distribution, but
remember that the money or new shares are being
paid or issued to you. The net asset value
fluctuates daily, along with the value of every
security in the portfolio.

Statement of Operations
This is the income statement, which details income
(mostly interest and
dividends earned) and expenses (including what you
pay us to manage your money). You'll also see
capital gains here--both realized and unrealized.

<PAGE>

Prudential Municipal Series Fund    New York Series
Getting the Most From Your Prudential Mutual Fund

Statement of Changes in Net Assets
This schedule shows how income and expenses
translate into changes
in net assets. The Fund is required to pay out the
bulk of its income to shareholders every year, and
this statement shows you how we do it (through
dividends and distributions) and how that affects
the net assets. This statement also shows how money
from investors flowed into and out of the Fund.

Notes to Financial Statements
This is the kind of technical material that can
intimidate readers, but it does contain useful
information. The Notes provide a brief history and
explanation of your Fund's objectives. In addition,
they outline how Prudential Mutual Funds prices
securities. The Notes also explain who manages and
distributes the Fund's shares and, more
importantly, how much they are paid for doing so.
Finally, the Notes explain how many shares are
outstanding and the number issued and redeemed over
the period.

Financial Highlights
This information contains many elements from prior
pages, but on a
per-share basis. It is designed to help you
understand how the Fund
performed, and to compare this year's performance
and expenses to those of prior years.

Independent Auditor's Report
Once a year, an outside auditor looks over our
books and certifies that the information is fairly
presented and complies with generally accepted
accounting principles.

Tax Information
This is information that we report annually about
how much of your total return is taxable. Should
you have any questions, you may want to consult a
tax adviser.

<PAGE>
www.prudential.com(800) 225-1852

Performance Comparison
These charts are included in the annual report and
are required by the Securities Exchange Commission.
Performance is presented here as a hypothetical
$10,000 investment in the Fund since its inception
or for 10 years (whichever is shorter). To help you
put that return in context, we
are required to include the performance of an
unmanaged, broad-based securities index as well.
The index does not reflect the cost of buying the
securities it contains or the cost of managing a
mutual fund. Of course, the index holdings do not
mirror those of the Fund--the index is a broad-based
reference point commonly used by investors to
measure how well they are doing. A definition of
the selected index is also provided. Investors
cannot invest directly in an index.

Prudential Municipal Series Fund    New York Series
Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/New York Money
Market Series seeks to provide the highest level of
current income that is exempt from New York State,
New York City, and federal income taxes, consistent
with liquidity and the preservation of capital. The
Series intends to invest in a portfolio of short-
term municipal debt securities with maturities of
13 months or less from the state of New York, its
municipalities, local governments, and other
qualifying issuers (such as Puerto Rico, Guam, and
the U.S. Virgin Islands).  There can be no
assurance that the Series will achieve its
investment objective.

Message From the Fund's President   As of April 17, 2000

(PHOTO)
Dear Shareholder
The Federal Reserve increased short-term interest
rates twice to slow U.S. economic growth and fend
off higher inflation during the six months that
ended on February 29, 2000. Prudential's Money
Markets Sector team worked hard to anticipate these
changes in U.S. monetary policy, and acted quickly
to take advantage of good investment opportunities
that emerged as New York money market yields rose.

As a result, Prudential Municipal Series Fund/New
York Money Market Series maintained a $1.00 net
asset value per share, and provided a competitive
yield during its fiscal half year. On February 29,
2000, the Series' seven-day current yield was
3.17%, compared with 3.11% for the average New York
money market fund as tracked by iMoneyNet, Inc. The
following report takes a closer look at
developments in the municipal money market sector
during the six-month review period, and explains
how the Series was positioned throughout.

New team member brings solid investment expertise
The newest member of Prudential's Money Markets
Sector team is Monica Wong. Prior to joining
Prudential, Monica was a portfolio manager at
Montgomery Asset Management, where she oversaw tax-
exempt assets totaling more than $500 million.
During Monica's 10 years of municipal finance
experience, she also worked as a research analyst,
financial advisor, trader, and underwriter.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Fed tried to curb U.S. economic growth
Shortly before the Series' fiscal half year began
on September 1, 1999, the Federal Reserve increased
the federal funds rate (what U.S. banks charge each
other for overnight loans) by a quarter of a
percentage point to 5.25% from 5.00%. It also
raised the rate at which banks can borrow from the
Federal Reserve system (known as the discount rate)
to 4.75% from 4.50%.

The short-term rate hike rippled through the U.S.
economy, increasing borrowing costs for consumers
and businesses. In this way, the Fed hoped to rein
in the brisk pace of U.S. economic growth and avert
a buildup in inflationary pressures. Mounting
inflation is particularly hard on people who live
on fixed incomes, because their buying power
declines if their incomes are not adjusted for the
rise in prices.

Reinvesting at higher yields helped the Series
Because we believed that the Fed would continue to
tighten monetary policy, we invested primarily in
shorter-term New York money market securities from
September 1999 through much of November 1999. As
these securities matured, we planned to reinvest
this money at the higher tax-exempt money market
yields that would likely be available after any
subsequent Fed rate hike.

We did not have to wait long. The U.S. central bank
boosted the federal funds rate to 5.50% and its
discount rate to 5.00% on November 16, 1999. Yields
on New York money market securities also climbed,
creating many attractive buying opportunities.

Prudential Municipal Series Fund   New York Money Market Series
Performance Review

Among our purchases were one-year tax anticipation
notes. Buying these securities in December 1999
lengthened the Series' weighted average maturity
(WAM), which positioned the Series longer than the
average of comparable funds as measured by
iMoneyNet, Inc. (WAM is a measurement tool that
determines a portfolio's sensitivity to changes in
the level of interest rates. It takes into account
the maturity level of each security held in a
portfolio.) Extending the Series' WAM by purchasing
these attractively priced securities enhanced the
Series' yield.

New year brought good buying opportunities
We again lengthened the Series' WAM in January 2000
by purchasing two kinds of bonds, both of which
provided attractive yields and were good
alternatives to tax-exempt notes and other
conventional municipal money market securities. We
bought one-year "prerefunded" bonds that are backed
by direct obligations of the U.S. government. We
also purchased one-year bonds that were rated AAA
because their interest and principal payments are
insured by a major bond insurance company. These
insured short-term bonds provided solid yields to
compensate for the fact that they were issued in
moderate-sized blocks. We, like most money
managers, often prefer to buy large blocks of bonds
because they could be easier to sell. However,
owning moderate-sized blocks of insured short-term
municipal bonds that offered higher yields met our
fundamental buy-and-hold strategy.

New York State bonds upgraded
On February 2, 2000, the Fed renewed its efforts to
check the powerful U.S. economy by raising the
federal funds rate to 5.75% and its discount rate
to 5.25%.  February marked the 107th consecutive
month of the economic expansion, making it the
longest in U.S. history.

At the state level, slow but steady economic growth
in New York was one of the reasons cited by
Standard & Poor's (S&P) when it upgraded
the state's general obligation bond rating to A-
plus from single-A on November 9, 1999. S&P also
noted the fundamental changes in New York's

fiscal discipline and management, as well as
marginal success in reducing the state's pace of
borrowing.

Looking Ahead
On March 21, 2000, the Fed increased the federal
funds rate to 6.00% and the discount rate to 5.50%.
As the U.S. economy continues to grow rapidly, we
believe this will not be the last time the Fed will
take action this year.

With the approach of the tax season, we intend to
again increase the Series' exposure to very short-
term municipal money market securities in order to
accommodate seasonal cash outflows that usually
occur as shareholders pay their income taxes.
Adopting this strategy should position the Series
to lock in higher yields that become available as
the supply of municipal money market securities
balloons during the tax season.

       Prudential Municipal Series Fund      New York Money Market Series
             Notes to Financial Statements (Unaudited)
      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940 as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of
eleven series. The monies of each series are invested in separate, independently
managed portfolios. The New York Money Market Series (the 'Series') commenced
investment operations in April, 1985. The Series is diversified and seeks to
achieve its investment objective of providing the highest level of income that
is exempt from New York State, New York City and federal income taxes with a
minimum of risk by investing in 'investment grade' tax-exempt securities having
a maturity of 13 months or less whose ratings are within the two highest ratings
categories by two nationally recognized statistical rating organizations, or if
not rated, are of comparable quality. The ability of the issuers of the
securities held by the Series to meet their obligations may be affected by
economic developments in a specific state, industry or region.
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.
      Securities Valuations:    Portfolio securities of the Series are valued at
amortized cost, which approximates market value. The amortized cost method of
valuation involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of any discount or
premium.
      All securities are valued as of 4:30 p.m., New York time.
      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of investments are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. Expenses are recorded on the accrual basis which
may require the use of certain estimates by management.
      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason, no federal income tax provision is
required.
      Dividends:    The Series declares daily dividends from net investment
income. Payment of dividends is made monthly. Income distributions and capital
gain distributions are determined in accordance with income tax regulations
which may differ from generally accepted accounting principles.
                                                                          15

<PAGE>
       Prudential Municipal Series Fund      New York Money Market Series
             Notes to Financial Statements (Unaudited) Cont'd.
      Custody Fee Credits:    The Fund has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC. ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation of officers of the Fund, occupancy and certain clerical
and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.
      The management fee paid to PIFM is computed daily and payable monthly, at
an annual rate of .50 of 1% of the average daily net assets of the Series.
      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS') which acts as the distributor of the Fund. The
Fund compensated PIMS for distributing and servicing the Fund's shares pursuant
to the plans of distribution regardless of expenses actually incurred by them.
The Series reimburses PIMS for distributing and servicing the Series' shares
pursuant to the plan of distribution at an annual rate of .125 of 1% of the
Series' average daily net assets. The distribution fees are accrued daily and
payable monthly.
      PIFM, PIMS and PIC are wholly owned subsidiaries of The Prudential
Insurance Company of America ('Prudential').
Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $45,000 for the services of
PMFS. As of February 29, 2000, approximately $7,500 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations include
certain out-of-pocket expenses paid to nonaffiliates.

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/North Carolina
Series' investment objective is to maximize current
income that is exempt from North Carolina State and
federal income taxes, consistent with the
preservation of capital. However, certain
shareholders may be subject to the federal
alternative minimum tax (AMT) because some of the
Series' bonds are AMT eligible. There can be no
assurance the Series will achieve its investment
objective.

Message From the Fund's President   As of April 17, 2000

(PHOTO)
Dear Shareholder,
The Class A shares of Prudential Municipal Series
Fund/North Carolina Series had a negative return of
0.86% during its fiscal half year that ended
February 29, 2000. For the same period, the Series'
benchmark Lipper Average was a negative 1.16%.
After the initial sales charge, the Class A shares'
return was a negative 3.84%. Prices of municipal
bonds declined primarily because investors required
higher yields in light of two short-term rate
increases implemented by the Federal Reserve during
our review period to slow the rapid pace of U.S.
economic growth.

Staying the course amid ups and downs of financial
markets

Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Prudential Municipal Series Fund   North Carolina Series
Performance Review

(PHOTO) (PHOTO) Portfolio Managers Evan Lamp (Municipal
                Bonds Sector Team Leader) and Lorely Machin

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest
rates by the Federal Reserve and sales of municipal
bonds by investors who wanted to realize tax losses
pressured the prices of tax-exempt debt securities.
Given this bearish trend, we positioned the Series
so that it would be less vulnerable to the decline
in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also engineered two quarter-point increases that raised
its discount rate on loans to banks from the
Federal Reserve system to 5.25% by February 2000.
As short-term rates rose, investors required higher
yields on both short- and long-term municipal
bonds, which caused their prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvest in new bonds or other bond funds
with a lower cost basis for tax purposes (due to
the higher level of yields). This is called "tax
loss swapping." In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

Prudential Municipal Series Fund   North Carolina Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase the Series'
distribution yield in this rising-interest-rate
environment. An increased exposure to the
transportation sector, retirement community bonds,
and others benefited the Series' yield.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally
provides some degree of protection by making the
portfolio less sensitive to the rise in bond
yields. (Duration measures how much a portfolio's
bonds will fluctuate in price for a given change in
interest rates. It is expressed
in years.) We kept the Series' duration shorter
than average for most of its
fiscal half year. This approach helped the Series'
share classes, without sales charges factored in,
to perform better than its benchmark Lipper
Average, which does not consider sales charges.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

We also maintained a considerable exposure to
prerefunded bonds, which made up 23.5% of the
Series' total investments as of February 29, 2000.
Prices of prerefunded bonds held up better due to
their high coupon rates and shorter-term
maturities.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for investors

who might want to buy them. Here's how it works:
When yields climb beyond a certain point for every
municipal bond, the market discount on that bond
may become subject to ordinary income taxes for new
buyers.

This lowers the value of the bond because new
buyers would want to purchase the bond cheaply
enough to compensate for the greater tax liability.

Looking Ahead
Shortly after our six-month review period ended,
the Fed engineered another quarter-point rate hike
that raised its target for the federal funds rate
to 6.00% and its discount rate to 5.50%. We believe
the Fed's efforts to tighten monetary policy will
slow the U.S. economic expansion in 2000 from its
7.30% annual pace in the fourth quarter of 1999.
Moderating economic growth could help bolster the
performance of municipal bonds, but detract from
the performance of equities.

Meanwhile, the powerful U.S. economic expansion has
improved the credit quality of many state and local
governments and reduced their borrowing needs,
allowing them to issue fewer bonds. The supply of
new municipal bonds has also decreased because the
rising-interest-rate environment has provided less
opportunity for issuers to save money by replacing
older higher-coupon bonds with new lower-coupon
bonds. With the declining supply, if investor
demand remains strong, the tax-exempt bond market
should perform better than other U.S. fixed-income
markets in 2000.

             Notes to Financial Statements (Unaudited)

      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of 11
series. The monies of each series are invested in separate, independently
managed portfolios. The North Carolina Series (the 'Series') commenced
investment operations in February 1985. The Series is diversified and its
investment objective is to maximize current income that is exempt from North
Carolina State and federal income taxes consistent with the preservation of
capital and, in conjunction therewith, the Series may invest in debt securities
with the potential for capital gain. The Series seeks to achieve this objective
by investing primarily in North Carolina State, municipal and local government
obligations and obligations of other qualifying issuers. The ability of the
issuers of the securities held by the Series to meet their obligations may be
affected by economic or political developments in a specific state, industry or
region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.

      Securities Valuations:    The Series values municipal securities
(including commitments to purchase such securities on a 'when-issued' basis) on
the basis of prices provided by a pricing service which uses information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining values. If market quotations are not readily available
from such pricing service, a security is valued at its fair value as determined
under procedures established by the Trustees.

      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost which approximates market value.

      All securities are valued as of 4:15 p.m., New York time.

      Financial Futures Contracts:    A financial futures contract is an
agreement to purchase (long) or sell (short) an agreed amount of securities at a
set price for delivery on a future date. Upon entering into a financial futures
contract, the Series is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Series each day, depending on
the daily fluctuation in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or

loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.

      The Series invests in financial futures contracts in order to hedge its
existing portfolio securities, or securities the Series intends to purchase,
against fluctuations in value caused by changes in prevailing interest rates.
Should interest rates move unexpectedly, the Series may not achieve the
anticipated benefits of the financial futures contracts and may realize a loss.
The use of futures transactions involves the risk of imperfect correlation in
movements in the price of futures contracts, interest rates and the underlying
hedged assets.

      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and accretes
original issue discount on portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.

      Net investment income (other than distribution fees) and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.

      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason no federal income tax provision is
required.

      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends is made monthly. Distributions of
net capital gains, if any, are made annually.

      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.

      Custodian Fee Credits:    The Series has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.

Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment
                                                                          15

Corporation ('PIC'); PIC furnishes investment advisory services in connection
with the management of the Fund. PIFM pays for the services of PIC, the cost of
compensation of officers of the Fund, occupancy and certain clerical and
bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.

      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS') which acts as the distributor of the Class A,
Class B and Class C shares of the Fund. The Fund compensated PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares,
pursuant to plans of distribution (the 'Class A, B and C Plans'), regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly.

      Pursuant to the Class A, Class B and Class C Plans, the Fund compensates
PIMS for distribution-related activities at an annual rate of up to .30 of 1%,
 .50 of 1% and 1%, of the average daily net assets of the Class A, Class B and
Class C shares, respectively. Such expenses under the Plans were .25 of 1%, .50
of 1% and .75 of 1% of the average daily net assets of the Class A, Class B and
Class C shares, respectively, for the six months ended February 29, 2000.

      PIMS has advised the Series that it received approximately $700 in
front-end sales charges resulting from sales of Class A and Class C shares
during the six months ended February 29, 2000. From these fees, PIMS paid such
sales charges to affiliated broker-dealers, which in turn paid commissions to
salespersons and incurred other distribution costs.

      PIMS has advised the Series that during the six months ended February 29,
2000, it received approximately $13,700 in contingent deferred sales charges
imposed upon certain redemptions by Class B shareholders.

      PIFM, PIC and PIMS are wholly owned subsidiaries of The Prudential
Insurance Company of America.

      The Series, along with other affiliated registered investment companies
(the 'Funds'), entered into a syndicated credit agreement ('SCA') with an
unaffiliated lender. The maximum commitment under the SCA is $1 billion and
interest on any borrowings will be at market rates. For the period
3/11/99-3/9/00, the commitment fee on the unused portion of the credit facility
was .065 of 1%. Subsequent to March 9, 2000, the SCA was renewed with a maximum
commitment of $1 billion at a commitment fee of .080 of 1% of the unused portion
of the credit facility. The expiration date of the SCA is March 9, 2001. The
commitment fee is accrued and paid quarterly on a pro rata basis by the Funds.
Prior to March 11, 1999, the Funds had a

credit agreement with a maximum commitment of $200,000,000. The commitment fee
was .055 of 1% on the unused portion of the credit facility. The Fund did not
borrow any amounts during the six months ended February 29, 2000. The purpose of
the credit agreements is to serve as an alternative source of funding for
capital share redemptions.

Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $7,300 for the services of PMFS.
As of February 29, 2000, approximately $1,200 of such fees were due to PMFS.
Transfer agent fees and expenses in the Statement of Operations include certain
out-of-pocket expenses paid to nonaffiliates.

Note 4. Portfolio Securities
Purchases and sales of portfolio securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000 were $5,807,679 and
$10,689,165, respectively.

      The cost basis of investments for federal income tax purposes at February
29, 2000, was substantially the same as for financial reporting purposes and
accordingly, net unrealized appreciation of investments for federal income tax
purposes was $192,684 (gross unrealized appreciation-$1,041,691; gross
unrealized depreciation-$849,007).

Note 5. Capital
The Series offers Class A, Class B and Class C shares. Class A shares are sold
with a front-end sales charge of up to 3%. Class B shares are sold with a
contingent deferred sales charge which declines from 5% to zero depending on the
period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% and a contingent deferred sales charge of 1% during the first
18 months. Class B shares will automatically convert to Class A shares on a
quarterly basis approximately seven
                                                                          17

years after purchase. A special exchange privilege is also available for
shareholders who qualify to purchase Class A shares at net asset value.

      The Fund has authorized an unlimited number of shares of beneficial
interest of each class at $.01 par value per share.

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/Ohio Series'
investment objective is to maximize current income
that is exempt from Ohio State and federal income
taxes, consistent with the preservation of capital.
However, certain shareholders may be subject to the
federal alternative minimum tax (AMT) because some
of the Series' bonds are AMT eligible. There can be
no assurance the Series will achieve its investment
objective.

Message From the Fund's President   As of April 17, 2000

(PHOTO)
Dear Shareholder
The Class A shares of Prudential Municipal Series
Fund/Ohio Series had a negative return of 0.59%
during its fiscal half year that ended February 29,
2000. For the same period, the return on the
Series' benchmark Lipper Average was a negative
1.14%. After the initial sales charge, the Class A
shares' return was a negative 3.57%. Prices of
municipal bonds declined primarily because
investors required higher yields in light of two
short-term rate increases implemented by the
Federal Reserve during our review period to slow
the rapid pace of U.S. economic growth.

Staying the course amid ups and downs of financial
markets
Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

(PHOTO) (PHOTO)  Portfolio Managers Evan
Lamp (Municipal Bonds Sector Team Leader) and Scott Diamond

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest
rates by the Federal Reserve and sales of municipal
bonds by investors who wanted to realize tax losses
pressured the prices of tax-exempt debt securities.
Given this bearish trend, we positioned the Series
so that it would be less vulnerable to the decline
in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also engineered two quarter-point increases that raised
its discount rate on loans to banks from the
Federal Reserve system to 5.25% by February 2000.
As short-term rates rose, investors required higher
yields on both short- and long-term municipal
bonds, which caused their prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvest in new bonds or other bond funds
with a lower cost basis for tax purposes (due to
the higher level of yields). This is called "tax
loss swapping." In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

LLC and Lipper Inc. The cumulative total returns do
not take into account sales charges. The average
annual total returns do take into account
applicable sales charges. The Series charges a
maximum front-end sales charge of 3% for Class A
shares and a declining contingent deferred sales
charge (CDSC) of 5%, 4%, 3%, 2%, 1%, and 1% for six
years for Class B shares. Class B shares will
automatically convert to Class A shares, on a
quarterly basis, approximately seven years after
purchase. Class C shares are subject to a front-end
sales charge of 1% and a CDSC for 18 months.
Without waiver of management fees and/or expense
subsidization, the Series' cumulative and average
annual total returns would have been lower, as
indicated in parentheses ( ).

Prudential Municipal Series Fund   Ohio Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase its distribution
yield in this rising-interest-rate environment.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally
provides some degree of protection by making the
portfolio less sensitive to the rise in bond
yields. (Duration measures how much a portfolio's
bonds will fluctuate in price for a given change in
interest rates. It is expressed in years.) Keeping
the Series' duration shorter than average for most
of our fiscal half year helped its share classes, without
sales charges factored in, to perform better than
its benchmark Lipper Average, which does not
consider sales charges.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

The Series' relative performance also benefited
because it holds bonds of the Franciscan Medical
Center that rallied. The Medical Center, located in
Dayton, Ohio, merged with another hospital, Bon
Secours, and is cutting its borrowing costs by
retiring its bonds on their first call date. These
bonds rated BBB gained in value because they now
have a shorter maturity and are backed by an escrow
consisting of direct obligations of the U.S.
government that are rated AAA.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for
investors who might want to buy them.  Here's how
it works: When yields climb beyond a certain point
for every municipal bond, the market discount on
that bond may become subject to ordinary income
taxes for new buyers. This lowers the value of the
bond because new buyers would want to purchase the
bond cheaply enough to compensate for the greater
tax liability.

Looking Ahead
Shortly after our six-month review period ended,
the Fed engineered another quarter-point rate hike
that raised its target for the federal funds rate
to 6.00% and its discount rate to 5.50%. We believe
the Fed's efforts to tighten monetary policy will
slow the U.S. economic expansion in 2000 from its
7.30% annual pace in the fourth quarter of 1999.
Moderating economic growth could help bolster the
performance of municipal bonds, but detract from
the performance of equities.

Meanwhile, the powerful U.S. economic expansion has
improved the credit quality of many state and local
governments and reduced their borrowing needs,
allowing them to issue fewer bonds. The supply of
new municipal bonds has also decreased because the
rising-interest-rate environment
provided less opportunity for issuers to save money
by replacing older
higher-coupon bonds with new lower-coupon bonds.
With the declining supply, if investor demand
remains strong, the tax-exempt bond market should
perform better than other U.S. fixed-income markets
in 2000.

       Prudential Municipal Series Fund      Ohio Series
             Notes to Financial Statements (Unaudited)

      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940, as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of
eleven series. The monies of each series are invested in separate, independently
managed portfolios. The Ohio Series (the 'Series') commenced investment
operations in September, 1984. The Series is diversified and its investment
objective is to maximize current income that is exempt from Ohio state and
federal income taxes consistent with the preservation of capital and, in
conjunction therewith, the Series may invest in debt securities with the
potential for capital gains. The Series seeks to achieve this objective by
investing primarily in Ohio state, municipal and local government obligations
and obligations of other qualifying issuers. The ability of the issuers of the
securities held by the Series to meet their obligations may be affected by
economic developments in a specific state, industry or region.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in preparation of its financial statements.
      Securities Valuation:    The Series values municipal securities (including
commitments to purchase such securities on a 'when-issued' basis) on the basis
of prices provided by a pricing service which uses information with respect to
transactions in bonds, quotations from bond dealers, market transactions in
comparable securities and various relationships between securities in
determining values. If market quotations are not readily available from such
pricing services, a security is valued at its fair value as determined under
procedures established by the Trustees.
      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost.
      All securities are valued as of 4:15 p.m., New York time.
      Financial Futures Contracts:    A financial futures contract is an
agreement to purchase (long) or sell (short) an agreed amount of securities at a
set price for delivery on a future date. Upon entering into a financial futures
contract, the Series is required to pledge to the broker an amount of cash
and/or other assets equal to a certain percentage of the contract amount. This
amount is known as the 'initial margin.' Subsequent payments, known as
'variation margin,' are made or received by the Series each day, depending on
the daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
    14

             Notes to Financial Statements (Unaudited) Cont'd.
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.
      The Series invests in financial futures contracts in order to hedge its
existing portfolio securities or securities the Series intends to purchase,
against fluctuations in value caused by changes in prevailing interest rates.
Should interest rates move unexpectedly, the Series may not achieve the
anticipated benefits of the financial futures contracts and may realize a loss.
The use of futures transactions involves the risk of imperfect correlation in
movements in the price of futures contracts, interest rates and the underlying
hedged assets.
      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and accretes
original issue discount paid on purchases of portfolio securities as adjustments
to interest income. Expenses are recorded on the accrual basis which may require
the use of certain estimates by management.
      Net investment income (other than distribution fees) and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.
      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason, no federal income tax provision is
required.
      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends are made monthly. Distributions of
net capital gains, if any, are made annually.
      Income distributions and capital gain distributions are determined in
accordance with income tax regulations which may differ from generally accepted
accounting principles.
      Custody Fee Credits:    The Fund has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.
      Reclassification of Capital Accounts:    The Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and
                                                                          15

Financial Statement Presentation of Income, Capital Gain, and Return of Capital
Distributions by Investment Companies. The effect of applying this statement was
to increase undistributed net investment income and increase accumulated net
realized loss on investments by $31,000, due to the sale of securities purchased
with market discount during the six months ended February 29, 2000. Net
investment income, net realized gains and net assets were not affected by this
change.

Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the cost of compensation of officers of the Fund, occupancy and certain clerical
and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.
      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.
      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Class A,
Class B and Class C shares of the Fund. The Fund compensated PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares
pursuant to plans of distribution, (the 'Class A, B and C Plans'), regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly.
      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1% of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plans were .25 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively,
for the six months ended February 29, 2000.
      PIMS has advised the Series that they received approximately $3,200 in
front-end sales charges resulting from sales of Class A shares during the six
months
    16

             Notes to Financial Statements (Unaudited) Cont'd.
ended February 29, 2000. From these fees, PIMS paid such sales charges to
affiliated broker-dealers, which in turn paid commissions to salespersons and
incurred other distribution costs.
      PIMS has advised the Series that for the six months ended February 29,
2000, they received approximately $14,100 and $300 in contingent deferred sales
charges imposed upon certain redemptions by Class B and Class C shareholders,
respectively.
      PIFM, PIC and PIMS are wholly owned subsidiaries of The Prudential
Insurance Company of America ('Prudential').
      The Fund, along with other affiliated registered investment companies (the
'Funds'), entered into a syndicated credit agreement ('SCA') with an
unaffiliated lender. The maximum commitment under the SCA is $1 billion and
interest on any borrowings will be at market rates. For the period
3/11/99-3/9/00, the commitment fee on the unused portion of the credit facility
was .065 of 1%. Subsequent to March 9, 2000, the SCA was renewed with a maximum
commitment of $1 billion at a commitment fee of .080 of 1% of the unused portion
of the credit facility. The expiration date of the SCA is March 9, 2001. The
commitment fee is accrued and paid quarterly on a pro rata basis by the Funds.
Prior to March 11, 1999, the Funds had a credit agreement with a maximum
commitment of $200,000,000. The commitment fee was .055 of 1% on the unused
portion of the credit facility. The Fund did not borrow any amounts during the
six months ended February 29, 2000. The purpose of the credit agreements is to
serve as an alternative source of funding for capital share redemptions.

Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $16,100 for the services of
PMFS. As of February 29, 2000, approximately $2,600 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations include
certain out-of-pocket expenses paid to nonaffiliates.

Note 4. Portfolio Securities
Purchases and sales of portfolio securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000 were $5,533,665 and
$10,889,824, respectively.
      The cost basis of investments for federal income tax purposes at February
29, 2000 was substantially the same as for financial reporting purposes and
accordingly, net unrealized appreciation of investments for federal income tax
purposes was
                                                                          17

$635,640 (gross unrealized appreciation--$2,383,063; gross unrealized
depreciation--$1,747,423).

Note 5. Capital
The Series offers Class A, Class B and Class C shares. Class A shares are sold
with a front-end sales charge of up to 3%. Class B shares are sold with a
contingent deferred sales charge which declines from 5% to zero depending on the
period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% and a contingent deferred sales charge of 1% during the first
18 months. Class B shares automatically convert to Class A shares on a quarterly
basis approximately seven years after purchase. A special exchange privilege is
also available for shareholders who qualify to purchase Class A shares at net
asset value.
      The Fund has authorized an unlimited number of shares of beneficial
interest of each class at $.01 par value per share.
      Transactions in shares of beneficial interest for the six months ended
February 29, 2000 and the fiscal year ended August 31, 1999 were as follows:

Getting the Most From Your Prudential Mutual Fund

When you invest through Prudential Mutual Funds,
you receive financial advice from a Prudential
Securities Financial Advisor or Pruco Securities
registered representative. Your advisor or
representative can provide you with the following
services:

There's No Reward Without Risk; but Is This Risk
Worth It?
Your financial advisor or registered representative
can help you match the reward you seek with the
risk you can tolerate. Risk can be difficult to
gauge--sometimes even the simplest investments bear
surprising risks. The educated investor knows that
markets seldom move in just one direction. There
are times when a market sector or asset class will
lose value or provide little in the way of total
return. Managing your own expectations is easier
with help from someone who understands the markets
and who knows you!

Keeping Up With the Joneses
A financial advisor or registered representative
can help you wade through the numerous available
mutual funds to find the ones that fit your
individual investment profile and risk tolerance.
While the newspapers and popular magazines are full
of advice about investing, they are aimed at
generic groups of people or representative
individuals--not at you personally. Your financial
advisor or registered representative will review
your investment objectives with you. This means you
can make financial decisions based on the assets
and liabilities in your current portfolio and your
risk tolerance--not just based on the current
investment fad.

Buy Low, Sell High
Buying at the top of a market cycle and selling at
the bottom are among the most common investor
mistakes. But sometimes it's difficult to hold on
to an investment when it's losing value every
month. Your financial advisor or registered
representative can answer questions when you're
confused or worried about your investment, and
should remind you that you're investing for the
long haul.

Investment Goals and Style
Prudential Municipal Series Fund/Pennsylvania
Series' investment objective is to maximize current
income that is exempt from Commonwealth of
Pennsylvania personal income and federal income
taxes, consistent with the preservation of capital.
However, certain shareholders may be subject to the
federal alternative minimum tax (AMT) because some
of the Series' bonds are AMT eligible. There can be
no assurance the Series will achieve its investment
objective.

Message From the Fund's President   As of April 17, 2000

(PHOTO)
Dear Shareholder
The Class A shares of Prudential Municipal Series
Fund/Pennsylvania Series had a negative return of
1.10%
during its fiscal half year that ended February 29,
2000. For the same period, the return on the
Series' benchmark Lipper Average was a negative
1.77%. After the initial sales charge, the Class A
shares' return was a negative 4.06%. Prices of
municipal bonds declined primarily because
investors required higher yields in light of two
short-term rate increases implemented by the
Federal Reserve during our review period to slow
the rapid pace of U.S. economic growth.

Staying the course amid ups and downs of financial
markets
Many investors consider selling an asset class that
has performed poorly in favor of investments that
are currently gaining in value. That may not be the
best move. Changes in asset allocation should
reflect basic shifts in an investor's time horizon
and tolerance for risk--not recent fluctuations in
the performance of financial markets. One strategy
may be to own a diversified portfolio of mutual
funds that invests in stocks, bonds, and money
market instruments because this approach may help
to reduce risk.

Deciding on the correct level of diversification is
not easy. It requires
an understanding of an investor's risk tolerance
and overall investment strategy. In these volatile
times, we recommend consulting your financial
advisor to develop your asset allocation goals.

Thank you for your continued confidence in
Prudential mutual funds.

Sincerely,

John R. Strangfeld
President
Prudential Municipal Series Fund

Performance Review

(PHOT) (PHOTO) Portfolio Managers Evan Lamp (Municipal Bonds
Sector Team Leader) and James M. Murphy

Bear market in municipal bonds continued
During our six-month review period, increases in
short-term interest rates by the Federal Reserve
and sales of municipal bonds by investors who
wanted to realize tax losses pressured the prices
of tax-exempt debt securities. Given this bearish
trend, we positioned the Series so that it would be
less vulnerable to the decline in bond prices.

The Fed raised its target for the federal funds
rate (what U.S. banks charge each other for
overnight loans) by a quarter of a percentage point
in November 1999 and February 2000 to curb U.S.
economic growth and reduce the economic imbalances
that can lead to higher inflation. These moves
pushed up the rate to 5.75% by February 2000. The
Fed also engineered two quarter-point increases
that raised its discount rate on loans
to banks from the Federal Reserve system to 5.25%
by February 2000. As short-term rates rose,
investors required higher yields on both short- and
long-term municipal bonds, which caused their
prices to fall.

More selling pressure emerged in late December
1999. As interest rates climbed, investors realized
capital losses by selling bonds or bond funds. Many
investors reinvest in new bonds or other bond funds
with a lower cost basis for tax purposes (due to
the higher level of yields). This is called "tax
loss swapping." In the municipal bond market, the
capital loss often reduces taxes, while the higher
yields on the new bonds or other funds are
generally tax exempt.

Prudential Municipal Series Fund   Pennsylvania Series
Performance Review

Although the bear market detracted from the Series'
returns, we were able to increase its distribution
yield in this rising-interest-rate environment.

We pursued a short-duration strategy
When bond markets sell off, lowering a portfolio's
duration generally provides some degree of
protection by making the portfolio less sensitive
to the rise in bond yields. (Duration measures how
much a portfolio's bonds will fluctuate in price
for a given change in interest rates. It is
expressed in years.) Keeping the Series' duration
shorter than average for most of our
fiscal half year helped its share classes, without
sales charges factored in, to perform better than
its Lipper Average, which does not consider sales
charges.

In January 2000, however, we began to lengthen the
Series' duration because we believe the Fed's
monetary policy moves will keep inflation in check,
which could allow municipal bond yields to decline
as the year progresses.

The Series was also helped by its considerable
exposure to prerefunded bonds, which stood at 20%
of its total investments as of February 29, 2000.
Prices of prerefunded bonds held up better due to
their high coupon rates and shorter-term
maturities.

We lessened the impact of "market-discount
taxation"
Another strategy that benefited the Series was
selling some of its municipal bonds before they
became subject to ordinary income taxes for
investors who might want to buy them. Here's how it
works: When yields climb beyond a certain point for
every municipal bond, the market discount on that
bond may become subject to ordinary income taxes
for new buyers.

This lowers the value of the bond because new
buyers would want to purchase the bond cheaply
enough to compensate for the greater tax liability.

Looking Ahead
Shortly after our six-month review period ended,
the Fed engineered
another quarter-point rate hike that raised its
target for the federal funds rate to 6.00% and its
discount rate to 5.50%. We believe the Fed's
efforts to
tighten monetary policy will slow the U.S. economic
expansion in 2000 from its 7.30% annual pace in the
fourth quarter of 1999. Moderating economic growth
could help bolster the performance of municipal
bonds, but detract from the performance of
equities.

Meanwhile, the powerful U.S. economic expansion has
improved the credit quality of many state and local
governments and reduced their borrowing needs,
allowing them to issue fewer bonds. The supply of
new municipal bonds has also decreased because the
rising-interest-rate environment provided less
opportunity for issuers to save money by replacing
older higher-coupon bonds with new lower-coupon
bonds. With the declining supply, if investor
demand remains strong, then the tax-exempt bond
market should perform better than other U.S. fixed-
income markets in 2000.

       Prudential Municipal Series Fund      Pennsylvania Series
             Notes to Financial Statements (Unaudited)
      Prudential Municipal Series Fund (the 'Fund') is registered under the
Investment Company Act of 1940 as an open-end investment company. The Fund was
organized as a Massachusetts business trust on May 18, 1984 and consists of 11
series. The monies of each series are invested in separate, independently
managed portfolios. The Pennsylvania Series (the 'Series') commenced investment
operations on April 3, 1987. The Series is diversified and seeks to achieve its
investment objective of obtaining the maximum amount of income exempt from
federal and applicable state income taxes with a minimum of risk by investing in
'investment grade' tax-exempt securities whose ratings are within the four
highest ratings categories by a nationally recognized statistical rating
organization or, if not rated, are of comparable quality. The ability of the
issuers of the securities held by the Series to meet their obligations may be
affected by economic or political developments in a specific state, industry or
region.
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.
      Securities Valuations:    The Series values municipal securities
(including commitments to purchase such securities on a 'when-issued' basis) on
the basis of prices provided by a pricing service which uses information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining values. If market quotations are not readily available
from such pricing service, a security is valued at its fair value as determined
under procedures established by the Trustees.
      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost.
      All securities are valued as of 4:15 p.m., New York time.
      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized gains and losses on sales
of securities are calculated on the identified cost basis. Interest income is
recorded on the accrual basis. The Series amortizes premiums and original issue
discount paid on purchases of portfolio securities as adjustments to interest
income. Expenses are recorded on the accrual basis which may require the use of
certain estimates by management.
      Net investment income (other than distribution fees) and unrealized and
realized gains or losses are allocated daily to each class of shares based upon
the relative proportion of net assets of each class at the beginning of the day.

       Prudential Municipal Series Fund      Pennsylvania Series
             Notes to Financial Statements (Unaudited) Cont'd.
      Federal Income Taxes:    For federal income tax purposes, each series in
the Fund is treated as a separate taxpaying entity. It is the intent of the
Series to continue to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its net
income to shareholders. For this reason no federal income tax provision is
required.
      Dividends and Distributions:    The Series declares daily dividends from
net investment income. Payment of dividends are made monthly. Distributions of
net capital gains, if any, are made annually. Income distributions and capital
gain distributions are determined in accordance with income tax regulations
which may differ from generally accepted accounting principles.
      Custody Fee Credits:    The Series has an arrangement with its custodian
bank, whereby uninvested monies earn credits which reduce the fees charged by
the custodian.
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
the compensation of officers of the Fund, occupancy and certain clerical and
bookkeeping costs of the Fund. The Fund bears all other costs and expenses.
      The management fee paid PIFM is computed daily and payable monthly, at an
annual rate of .50 of 1% of the average daily net assets of the Series.
      The Fund had a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Class A,
Class B and Class C shares of the Fund. The Fund compensated PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares,
pursuant to plans of distribution, (the 'Class A, B and C Plans'), regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly.
      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1%
and 1%, of the average daily net assets of the Class A, B and C shares,
respectively. Such expenses under the Plan were .25 of 1%, .50 of 1% and .75 of
1% of the average daily net assets of the Class A, B and C shares, respectively.
      PIMS has advised the Series that they have received approximately $4,400
and $600 in front-end sales charges resulting from sales of Class A and Class C
shares,
                                                                          17

respectively during the six months ended February 29, 2000. From these fees,
PIMS paid such sales charges to affiliated broker-dealers, which in turn paid
commissions to salespersons and incurred other distribution costs.
      PIMS has advised the Series that for the six months ended February 29,
2000, they received approximately $53,700 and $1,900 in contingent deferred
sales charges imposed upon certain redemptions by Class B and Class C
shareholders, respectively.
      PIFM, PIC and PIMS are wholly owned subsidiaries of The Prudential
Insurance Company of America.
      As of March 11, 1999, the Series, along with other affiliated registered
investment companies (the 'Funds'), entered into a syndicated credit agreement
('SCA') with an unaffiliated lender. The maximum commitment under the SCA is $1
billion. Interest on any borrowings will be at market rates. For the period
3/11/99 - 3/9/00, the commitment fee on the unused portion of the credit
facility was .065 of 1%. Subsequent to March 9, 2000, the SCA was renewed with a
maximum commitment of $1 billion at a commitment fee of .080 of 1% of the unused
portion of the facility. The expiration date of the SCA is March 9, 2001. The
Fund did not borrow any amounts pursuant to either agreement during the six
months ended February 29, 2000. The purpose of the credit agreements is to serve
as an alternative source of funding for capital share redemptions.
Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), a wholly owned subsidiary of PIFM,
serves as the Fund's transfer agent. During the six months ended February 29,
2000, the Series incurred fees of approximately $44,600 for the services of
PMFS. As of February 29, 2000, approximately $7,300 of such fees were due to
PMFS. Transfer agent fees and expenses in the Statement of Operations includes
certain out-of-pocket expenses paid to nonaffiliates.
Note 4. Portfolio Securities
Purchases and sales of portfolio securities of the Series, excluding short-term
investments, for the six months ended February 29, 2000 were $13,407,200 and
$23,875,522, respectively.
      The cost basis of investments for federal income tax purposes at February
29, 2000 was substantially the same as for financial reporting purposes and
accordingly, net unrealized depreciation of investments for federal income tax
purposes was $1,769,326 (gross unrealized appreciation--$5,436,656; gross
unrealized depreciation--$7,205,982).

Note 5. Capital
The Series offers Class A, Class B and Class C shares. Class A shares are sold
with a front-end sales charge of up to 3%. Class B shares are sold with a
contingent deferred sales charge which declines from 5% to zero depending on the
period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% during the first 18 months. Class B shares will automatically
convert to Class A shares on a quarterly basis approximately seven years after
purchase. A special exchange privilege is also available for shareholders who
qualify to purchase Class A shares at net asset value. The Fund has authorized
an unlimited number of shares of beneficial interest of each class at $.01 par
value per share.
      Transactions in shares of beneficial interest for the six months ended
February 29, 2000 and the fiscal year ended August 31, 1999 were as follows:

Getting the Most From Your Prudential Mutual Fund

How many times have you read these reports--or other
financial materials--and stumbled across a word that
you don't understand?
Many shareholders have run into the same problem.
We'd like to help. So we'll use this space from
time to time to explain some of the words you might
have read, but not understood. And if you have a
favorite word that no one can explain to your
satisfaction, please write to us.
Basis Point: 1/100th of 1%. For example, one-half
of one percent is 50 basis points.
Collateralized Mortgage Obligations (CMOs):
Mortgage-backed bonds that separate mortgage pools
into different maturity classes called tranches.
These instruments are sensitive to changes in
interest rates and homeowner refinancing activity.
They are subject to prepayment and maturity
extension risk.
Derivatives: Securities that derive their value
from other securities. The rate of return of these
financial instruments rises and falls--sometimes
very suddenly--in response to changes in some
specific interest rate, currency, stock, or other
variable.
Discount Rate: The interest rate charged by the
Federal Reserve on loans to member banks.
Federal Funds Rate: The interest rate charged by
one bank to
another on overnight loans.
Futures Contract: An agreement to purchase or sell
a specific amount of
a commodity or financial instrument at a set price
at a specified date in
the future.
