TO OUR SHAREHOLDERS:


For the six-month period ended September 30, 1996, CMA Pennsylvania
Municipal Money Fund paid shareholders a net annualized yield of
2.86%*. As of September 30, 1996, the Fund's 7-day yield was 3.01%.

The Environment
Although the US stock and bond markets rallied late in the six-month
period ended September 30, 1996, much of the period was marked by
volatility in the capital markets. The US economy demonstrated
surprising resilience during the first half of the year. As a
result, when economic data releases appeared to indicate that the US
economy was expanding at a stronger-than-expected (and potentially
inflationary) rate, investors focused on the increasing possibility
of monetary policy tightening by the Federal Reserve Board. During
these periods, stock prices declined and long-term interest rates
moved higher. However, with inflationary pressures still under
control, the US central bank did not tighten monetary policy at its
September 24 meeting. This development, coupled with several
economic data releases that showed growth was at or below
expectations, helped to assuage investors' concerns about an
overheating economy. Stock and bond prices improved, with stock
market averages reaching historic high levels.
<PAGE>
The shifts in perceptions were exemplified by investors' reactions
to the release of recent employment reports. Inflationary concerns
were heightened in early July with the release of a stronger-than-
expected employment report for June. However, more subdued job
growth and decelerating hourly wage gains were subsequently reported
for the month of July. Although the employment report for August
showed that unemployment had dropped to its lowest level since 1989,
these results were generally in line with expectations, and were
received favorably by investors. The greatest boost in investor
confidence occurred in early October with the release of September's
employment report, which showed a slight increase in unemployment.

[FN]
*Based on a constant investment throughout the period, with
 dividends compounded daily, and reflecting a net return to the
 investor after all expenses.


Investors will continue to monitor economic data releases to
determine the probable direction of the US economy. The outcome of
the upcoming November election will also increasingly influence
investor psychology in the weeks ahead.

Investment Outlook and Strategy
Economic growth in the Commonwealth of Pennsylvania remained
positive during the six-month period ended September 30, 1996. After
a sharp increase earlier in the period, the pace of growth in the
manufacturing sector moderated. Although still positive, new orders
have begun to decline, and current shipments remain strong. In
addition, expectations about future growth have moderated from
earlier in the period. Finally, with an upbeat economic picture
during the six-month period, Pennsylvania's employment levels showed
modest improvement as the seasonally adjusted unemployment rate has
fluctuated around the national level.

This positive economic growth allowed the Commonwealth to finish its
fiscal year 1996 on a solid note with a positive General Fund
balance of $183.8 million, or $65.5 million above estimates.
Contributing to this positive balance was tax collections for fiscal
year 1996 coming in at $16.3 billion, which is $69.8 million above
estimates and $113.9 million above the previous fiscal year. These
positive results will increase the Commonwealth's "rainy-day" fund
by $27.6 million to $211 million. During the six-month period ended
September 30, 1996, a $16.4 billion General Fund budget was enacted
for fiscal year 1997. This new budget increases government spending
a modest six tenths of 1%, provides for a $15 million tax cut or job
creation tax credit for companies who add new employees, and
increases school funding by $138 million. Finally, Governor Ridge
continues to exercise spending restraint over Commonwealth
expenditures by eliminating 1,000 jobs from the government payroll.
<PAGE>
The positive revenue stream allowed the Commonwealth to pay off its
outstanding $500 million in tax anticipation notes (TAN) in June, as
well as supplement the various Pennsylvania school districts who
continue to issue a very moderate amount of tax and revenue
anticipation notes (TRAN).

As discussed in our annual report to shareholders dated March 31,
1996, CMA Pennsylvania Municipal Money Fund began the six-month
period ended September 30, 1996 with an average portfolio maturity
in the 40-day range, while preparing to meet tax-related redemptions
in April. Once tax-related redemptions ended, we began to extend the
Fund's holdings of tax-exempt commercial paper into July and August
while waiting for the issuance of the annual City of Philadelphia
and Philadelphia School District TRAN. This extension increased the
Fund's average life to the 50-day range, which helped to stabilize
the Fund's yield as supply imbalances in the months of June and July
adversely affected yields on variable rate demand notes. Despite
strong employment data reports, inflationary data continued to
remain favorable during this period. As it became clearer during the
period that the Federal Reserve Board might hold interest rates
steady with the Federal Funds rate at 5.25% and other economic data
started to suggest a slower pattern of growth, we began taking
advantage of a spike in yields and extended the Fund's average
portfolio maturity to the 60-day range. We utilized the Fund's
holdings of tax-exempt commercial paper and purchases of City of
Philadelphia and Philadelphia school district TRAN as the only
available methods to extend.

Looking ahead, we will continue to monitor the various economic data
as well as the Federal Reserve Board's intentions with regard to
monetary policy. As conditions warrant, we will maintain a slightly
aggressive approach to the market using the annual issuance of
Pennsylvania TAN as a means to extend the average life of the Fund
in preparation for a period of technical strength in the early part
of 1997. We will continue to monitor economic data, and should
inflation begin to increase or the Federal Reserve Board change its
monetary stance to a bias toward tightening, we will change the
Fund's strategy accordingly. We continue to look for opportunities
to diversify the portfolio, and we closely monitor credit quality
while seeking to offer shareholders an attractive tax-exempt yield.

In Conclusion
We thank you for your support of CMA Pennsylvania Municipal Money
Fund, and we look forward to serving your investment needs in the
future.

CMA PENNSYLVANIA MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS

<PAGE>
1. Significant Accounting Policies:
CMA Pennsylvania Municipal Money Fund (the "Fund") is part of CMA
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. These unaudited
financial statements reflect all adjustments which are, in the
opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a
normal recurring nature. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments--Investments are valued at amortized
cost, which approximates market value. For the purpose of valuation,
the maturity of a variable rate demand instrument is deemed to be
the next coupon date on which the interest rate is to be adjusted.
In the case of a floating rate instrument, the remaining maturity is
the demand notice payment period.

(b) 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.

(c) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income (including amortization of
premium and discount) is recognized on the accrual basis. Realized
gains and losses on security transactions are determined on the
identified cost basis.

(d) Prepaid registration fees--Prepaid registration fees are charged
to expense as the related shares are issued.

(e) Dividends and distributions to shareholders--The Fund declares
dividends daily and reinvests daily such dividends (net of non-
resident alien tax withheld) in additional fund shares at net asset
value. Dividends are declared from the total of net investment
income, excluding discounts earned other than original issue
discounts. Net realized capital gains, if any, are normally
distributed annually after deducting prior years' loss carryforward.
The Fund may distribute capital gains more frequently than annually
in order to maintain the Fund's net asset value at $1.00 per share.

2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM" or "Adviser"). 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.
<PAGE>
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: 0.50%
of the first $500 million of average daily net assets; 0.425% of
average daily net assets in excess of $500 million but not exceeding
$1 billion; and 0.375% of average daily net assets in excess of $1
billion.

Pursuant to the Distribution and Shareholder Servicing Plan in
compliance with Rule 12b-1 under the Investment Company Act of 1940,
Merrill Lynch, Pierce, Fenner & Smith Inc. ("MLPF&S") receives a
distribution fee from the Fund at the end of each month at the
annual rate of 0.125% of average daily net assets of the Fund. The
distribution fee is to compensate MLPF&S financial consultants and
