TO OUR SHAREHOLDERS

The Municipal Market Environment
During the six months ended July 31, 1999, long-term bond yields
rose significantly. Steady US economic growth combined with
improvement in foreign economies, most notably Japan and Brazil, as
well as an inflation scare in early May put upward pressure on bond
yields throughout the period. Continued strong US employment growth,
particularly the decline in the US unemployment rate to 4.2% in
early June, was among the reasons the Federal Reserve Board cited
for raising short-term interest rates in late June. US Treasury bond
yields reacted by climbing above 6.15% by late June before improving
somewhat to 6.10% by July 31, 1999. During the last six months,
yields on long-term US Treasury securities increased approximately
100 basis points (1.00%).

Long-term tax-exempt bond yields also rose during the last six
months. Until early May, the municipal bond market had been able to
withstand much of the upward pressure on bond yields. However,
investor concerns regarding ongoing US economic strength and the
fear of additional moves by the Federal Reserve Board eventually
pushed municipal bond yields higher throughout June and July. During
the period, the yields on long-term tax-exempt revenue bonds rose
almost 50 basis points to 5.65%, as measured by the Bond Buyer
Revenue Bond Index.

The ability of the tax-exempt bond market to withstand much of the
recent upward pressure on long-term fixed-income bond yields has
been a reflection of the continued strong technical position the
municipal bond market has enjoyed in recent quarters. During the
last six months, more than $120 billion in long-term municipal bonds
was underwritten, a decrease of more than 20% compared to the same
period a year ago. During the past three months, more than $60
billion in municipal bonds was underwritten. This quarterly issuance
represents a decline of nearly 25% compared to the same three-month
period in 1998.

Recently, the municipal supply position deteriorated even further.
Total issuance in July 1999 of $16.5 billion was more than 30% lower
than July 1998 levels. Additionally, in June and July, investors
received more than $40 billion in coupon income and proceeds from
bond maturities and early bond redemptions. These proceeds have
generated significant retail investor interest, easily absorbing the
recent diminished supply. This very favorable supply/demand position
allowed the tax-exempt bond market to outperform its taxable
counterpart in recent months.

However, the recent relative outperformance of the municipal bond
market has somewhat reduced the very attractive tax-exempt bond
yield ratios that were available at the end of 1998. In December
1998, long-term, uninsured municipal bond yields were higher than
those of their taxable counterparts. Historically, long-term tax-
exempt bond yields have been approximately 82%--85% of long-term US
Treasury bond yields. Municipal bond yields rose at a lower rate in
recent months than US Treasury bond yields, causing the yield ratio
to decline. At July 31, 1999, long-term municipal bond yields were
approximately 92% of their taxable counterparts. Current ratios,
while lower than those available at the end of 1998, still represent
historically attractive levels. We expect the municipal bond market
to maintain its strong technical position for the remainder of 1999.
Consequently, there appears to be little reason for the tax-exempt
bond market to underperform the taxable US Treasury bond market.
This suggests that the present bond yield ratio is likely to remain
stable in the coming months and a return to a ratio in excess of
100% of taxable Treasury securities is improbable.

Looking ahead, it appears to us that long-term municipal bond yields
will trade in a relatively tight range near current levels. Strong
US economic performance is being balanced by nearly negligible
inflation data, as well as improvements in productivity in both
manufacturing and service industries. Future moves by the Federal
Reserve Board have largely been discounted by bond markets and are
to a great extent reflected in present bond yields.



Merrill Lynch New Mexico Municipal Bond Fund

July 31, 1999



Any improvement in bond prices is likely to be contingent upon
weakening in both US employment growth and consumer spending. The
100 basis point rise in US Treasury bond yields seen thus far this
year is likely to negatively affect US economic growth. The US
housing market will be among the first sectors likely to be
affected, as some declines have already been evidenced because of
higher mortgage rates. We believe it is also unrealistic to expect
double-digit returns in US equity markets to continue indefinitely.
Much of the US consumer's wealth is tied to recent stock market
appreciation. Any slowing in these incredible growth rates is likely
to reduce consumer spending. These factors suggest that the worst of
the recent increase in bond yields has passed and stable, if not
slightly improving, bond prices may be expected.

Fiscal Year in Review
The Fund started the fiscal year ended July 31, 1999 fully invested
based on our expectations for steady economic growth and low
inflation. This scenario characterized the first six months of the
fiscal year. Therefore, we held a neutral-to-aggressive investment
posture for much of this period. We maintained the Fund's fully
invested position and structured the portfolio in an effort to
participate in any bond market rally, thus enhancing the total
return to shareholders. In addition, we carefully monitored our call
protection in order to seek to achieve ample tax-exempt income for
our shareholders for many years to come.

During the second half of the fiscal year, the combination of strong
growth and accelerating inflationary concerns caused the Federal
Reserve Board to raise short-term interest rates by 25 basis points.
Over the last few months of the fiscal year, we realized that both
growth and inflationary fears could negatively impact the bond
market. Therefore, we shifted our portfolio strategy. We adopted a
defensive position by reducing our exposure to the bond market and
by maintaining a cash reserve position of about 10%--15% of net
assets.

Looking ahead, we are seeking an opportune time to reenter the bond
market. Since long-term Treasury yields are now over 6% and long-
term municipal bonds are trading at approximately 95% of Treasury
issues (as compared to the historic average of between 85%--90%), we
are considering this opportunity to reinvest the Fund's cash
reserves at significantly higher yields than just a few months
earlier.

During the fiscal year ended July 31, 1999, our investment
strategies benefited the Fund's performance as the Fund had total
returns of +1.83%, +1.31%, +1.21% and +1.73% for Class A, Class B,
Class C and Class D Shares, respectively. (Complete performance
information can be found on pages 3-5 of this report to
shareholders.)

In Conclusion
We appreciate your ongoing interest in Merrill Lynch New Mexico
Municipal Bond Fund, and we look forward to serving your investment
needs in the months and years to come.

Sincerely,

PERFORMANCE DATA

About Fund Performance

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers four pricing
alternatives:

* Class A Shares incur a maximum initial sales charge (front-end
  load) of 4% and bear no ongoing distribution or account maintenance
  fees. Class A Shares are available only to eligible investors.

* Class B Shares are subject to a maximum contingent deferred sales
  charge of 4% if redeemed during the first year, decreasing 1% each
  year thereafter to 0% after the fourth year. In addition, Class B
  Shares are subject to a distribution fee of 0.25% and an account
  maintenance fee of 0.25%. These shares automatically convert to
  Class D Shares after approximately 10 years. (There is no initial
  sales charge for automatic share conversions.)

* Class C Shares are subject to a distribution fee of 0.35% and an
  account maintenance fee of 0.25%. In addition, Class C Shares are
  subject to a 1% contingent deferred sales charge if redeemed within
  one year of purchase.

* Class D Shares incur a maximum initial sales charge of 4% and an
  account maintenance fee of 0.10% (but no distribution fee).

None of the past results shown should be considered a representation
of future performance. Figures shown in the "Recent Performance
Results" and "Average Annual Total Return" tables assume
reinvestment of all dividends and capital gains distributions at net
asset value on the payable date. Investment return and principal
value of shares will fluctuate so that shares, when redeemed, may be
worth more or less than their original cost. Dividends paid to each
class of shares will vary because of the different levels of account
maintenance, distribution and transfer agency fees applicable to
each class, which are deducted from the income available to be paid
to shareholders.

Merrill Lynch New Mexico Municipal Bond Fund

July 31, 1999


NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch New Mexico Municipal Bond Fund (the "Fund") is part of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust"). The
Fund is registered under the Investment Company Act of 1940 as a non-
diversified, open-end management investment company. The Fund's
financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of
management accruals and estimates. The Fund offers four classes of
shares under the Merrill Lynch Select PricingSM System. Shares of
Class A and Class D are sold with a front-end sales charge. Shares
of Class B and Class C may be subject to a contingent deferred sales
charge. All classes of shares have identical voting, dividend,
liquidation and other rights and the same terms and conditions,
except that Class B, Class C and Class D Shares bear certain
expenses related to the account maintenance of such shares, and
Class B and Class C Shares also bear certain expenses related to the
distribution of such shares. Each class has exclusive voting rights
with respect to matters relating to its account maintenance and
distribution expenditures. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds and other portfolio
securities in which the Fund invests are traded primarily in the
over-the-counter municipal bond and money markets and are valued at
the last available bid price in the over-the-counter market or on
the basis of yield equivalents as obtained from one or more dealers
that make markets in the securities. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their
settlement prices as of the close of such exchanges. Short-term
investments with remaining maturities of sixty days or less are
valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or
under the direction of the Board of Trustees of the Trust, including
valuations furnished by a pricing service retained by the Trust,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Trust under the general supervision of the Trustees.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts
for the purpose of hedging the market risk on existing securities or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at
a specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the
contract is closed, the Fund records a realized gain or loss equal
to the difference between the value of the contract at the time it
was opened and the value at the time it was closed.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Deferred organization expenses and prepaid registration fees--
Deferred organization expenses are charged to expense on a straight-
line basis over a period not exceeding five years. Prepaid
registration fees are charged to expense as the related shares are
issued.

NOTES TO FINANCIAL STATEMENTS (concluded)

(f) Dividends and distributions--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded on the ex-dividend dates. Distributions in excess
of realized capital gains are due primarily to differing tax
treatments for futures transactions and post-October losses.


2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner. The Fund has also entered into a Distribution
Agreement and Distribution Plans with Merill Lynch Funds Distributor
("MLFD" or the "Distributor"), a division of Princeton Funds
Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary of
Merrill Lynch Group, Inc.

FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee based upon the average daily
value of the Fund's net assets at the following annual rates: .55%
of the Fund's average daily net assets not exceeding $500 million;
 .525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and .50% of average daily net assets in excess
of $1 billion.

For the year ended July 31, 1999, FAM earned fees of $71,016, of
which $51,648 was voluntarily waived.

Pursuant to the Distribution Plans adopted by the Fund in accordance
with Rule 12b-1 under the Investment Company Act of 1940, the Fund
pays the Distributor ongoing account maintenance and distribution
fees. The fees are accrued daily and paid monthly at annual rates
based upon the average daily net assets of the shares as follows:


                                     Account    Distribution
                                 Maintenance Fee     Fee

Class B                               .25%           .25%
Class C                               .25%           .35%
Class D                               .10%            --


Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML &
Co., also provides account maintenance and distribution services to
the Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
shareholders.

For the year ended July 31, 1999, MLFD earned underwriting discounts
and MLPF&S earned dealer concessions on sales of the Fund's Class A
and Class D Shares as follows:

                                         MLFD         MLPF&S

Class A                                  $129         $1,393
Class D                                  $ 29         $  375


For the year ended July 31, 1999, MLPF&S received contingent
deferred sales charges of $17,154 and $750 relating to transactions
in Class B and Class C Shares, respectively.

Financial Data Services, Inc., a wholly-owned subsidiary of ML &
Co., is the Fund's transfer agent.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or
directors of FAM, PSI, PFD, and/or ML & Co.

The Board of Trustees and Shareholders,
Merrill Lynch New Mexico Municipal Bond Fund of

We have audited the accompanying statement of assets and
liabilities, including the schedule of investments, of Merrill Lynch
New Mexico Municipal Bond Fund of Merrill Lynch Multi-State
Municipal Series Trust as of July 31, 1999, the related statements
of operations for the year then ended and changes in net assets for
each of the years in the two-year period then ended, and the
financial highlights for each of the years in the five-year period
then ended. These financial statements and the financial highlights
are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and the
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.
Our procedures included confirmation of securities owned at July 31,
1999 by correspondence with the custodian and broker. An audit also
includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights
present fairly, in all material respects, the financial position of
Merrill Lynch New Mexico Municipal Bond Fund of Merrill Lynch Multi-
State Municipal Series Trust as of July 31, 1999, the results of its
operations, the changes in its net assets, and the financial
highlights for the respective stated periods in conformity with
generally accepted accounting principles.
