TO OUR SHAREHOLDERS:


For the year ended March 31, 1997, CMA Pennsylvania Municipal Money
Fund paid shareholders a net annualized yield of 2.89%*. As of March
31, 1997, the Fund's 7-day yield was 2.83%.

Investment Outlook and Strategy
During the beginning of the six-month period ended March 31, 1997,
economic activity in the Commonwealth of Pennsylvania was relatively
stagnant. The manufacturing sector continued to grow, but at a
slightly slower pace than in recent months. Additionally,
nonresidential construction, while improving the first seven months
of 1996, declined as we approached 1996 year-end. During 1996,
payroll jobs increased less than 4%. However, despite the
commonwealth's economy moderating during the first half of the six-
month period, Pennsylvania continued to record solid tax
collections. Through the first half of fiscal year 1997,
Pennsylvania reported general revenue collections 6.5% above the
comparable period last year and 2% above budget estimates.
Consequently, the various Pennsylvania municipalities who also
benefited from this positive revenue stream continue to issue a
minimal amount of short-term municipal notes. As 1997 started,
January's State Business Outlook Survey suggested that manu-
facturing activity regained some momentum. According to the survey,
current economic activity returned to positive levels following a
negative reading in December 1996. The survey reflects that
manufacturing forecasts for the next six months point to continued
steady growth ahead. Specifically, the current General Activity
Index increased 11.3% in January 1997 from a revised reading of 6.2%
in December 1996.

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


During the six-month period ended March 31, 1997, economic
statistics continued to paint an ideal picture of the US economy.
For a majority of the period, a combination of steady growth and low
inflation kept Federal Reserve Board policymakers on hold. For
example, despite strong holiday sales spurred by healthy increases
in personal income, the consensus remained that monetary policy
would be on hold for the near term. However, during most of this
period, a lack of fixed-rate supply combined with traditional
inflows during early December 1996 and January 1997 kept yields on
fixed-rate notes relatively unattractive compared to those on
variable rate demand notes. Both the flat short-term tax-exempt
yield curve and a bias for tighter monetary policy caused us to use
the Fund's commercial paper to maintain a relatively neutral average
portfolio maturity, while selectively purchasing fixed-rate notes
when yields were attractive. The Fund had also used this strategy
during the six-month period ended September 30, 1996, since similar
conditions prevailed during that time period. Furthermore, the
purchase of fixed-rate notes at attractive levels during July 1996
and August 1996 enhanced the Fund's performance for the recent
fiscal year.
<PAGE>
As the six-month period ended March 31, 1997 concluded, continued
strength in a majority of economic statistics revealed the potential
for impressive growth during the first quarter of 1997. Therefore,
with the likelihood of an interest rate hike and the expected rise
in yields on variable rate products in April because of outflows
during tax time, we decided to position the Fund more defensively.
In October 1996, the average portfolio maturity was in the 45-day
range, but by the end of March, the average portfolio maturity was
in the 40-day range. On March 25, 1997, the Federal Reserve Board
increased the Federal Funds rate by 25 basis points (0.25%) to 5.5%.
During the six-month period ended March 31, 1997, Pennsylvania's
short-term issuance totaled $1.2 billion. Diversification and credit
quality remain paramount to the Fund, and we will continue to
closely monitor the everchanging marketplace.

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
months and years ahead.

Sincerely,








(Arthur Zeikel)

CMA PENNSYLVANIA MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS


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. 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.
<PAGE>
(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 and back-up withholding 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.

(f) Reclassification--Generally accepted accounting principles
require that certain components of net assets be adjusted to reflect
permanent differences between financial and tax reporting.
Accordingly, current year's permanent book/tax differences of $3,087
have been reclassified between accumulated net realized capital
