TO OUR SHAREHOLDERS:

For the six-month period ended September 30, 1994, CMA Arizona
Municipal Money Fund paid shareholders a net annualized yield of
2.32%*. As of September 30, 1994, the Fund's 7-day yield was 3.07%.

The Environment
Concerns of increasing inflationary pressures continued to prompt
volatility in the US stock and bond markets during the July--
September period. In addition, the weakness of the US dollar in
foreign exchange markets caused intermittent stock and bond market
declines during the period. While the immediate concerns regarding
the US dollar had diminished by late July, the possibility of
continued tightening by the Federal Reserve Board persisted for most
of the period. However, a lower-than-expected rate of growth
reported for the US economy during the second calendar quarter
allayed inflationary concerns to some degree, despite the fifth
increase this year in short-term interest rates made by the central
bank in mid-August. Inflationary expectations surfaced again with
the announcement of significant upward revision in industrial
production and capacity utilization for the May--July period. When
the central bank did not raise short-term interest rates at the late
September Federal Open Market Committee meeting, financial markets
rallied on the expectation that the US economy was not overheating
and therefore significant further monetary policy tightening would
not be necessary.

Despite the stronger-than-expected industrial production results,
other economic data suggest that while the economic recovery is
continuing, it is losing some momentum. Consumer spending is
increasing, but at a relatively slow pace, and existing home sales
may have peaked. Inflation remains subdued at the retail level. In
the industrial sector, the sharp increase in manufacturing
production in August was largely the result of a strong increase in
motor vehicle assemblies, which may level off in the weeks ahead. On
balance, it appears that the growth in US industry is progressing at
a steady, modest rate.

Despite evidence of a moderating trend in the US economy, Chairman
Greenspan indicated in his July Humphrey-Hawkins testimony that the
central bank would prefer to err on the side of too much monetary
tightening rather than too little. In the weeks ahead, investors
will continue to assess economic data and inflationary trends in
order to gauge whether further increases in short-term interest
rates are imminent. Continued indications of moderate and
sustainable levels of economic growth would be positive for the US
capital markets.

Investment Outlook and Strategy
During the six-month period ended September 30, 1994, the US economy
continued to surprise the marketplace with its resiliency.
Manufacturing provided a strong catalyst for growth, and continued
strength in housing and automobile sales provided the impetus for
the Federal Reserve Board to continue the restrictive monetary
policy it initiated in February. This was accomplished by raising
the Federal Funds rate in April by 25 basis points (0.25%) to 3.75%.
More aggressive increases of 50 basis points followed in May and
August, pushing the Federal Funds rate to its current level of
4.75%. In addition, the Federal Reserve Board raised the discount
rate by 50 basis points in both May and August. The yield on the
one-year US Treasury bill rose approximately 155 basis points to
5.95% by September 30, 1994.

*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 September 30, 1994, the State of
Arizona continued to maintain solid economic growth. The State is
profiting from a strong high-technology sector, active construction
markets and solid tourism activity. As a result, measured on a year-
over-year basis ending July 1994, Arizona ranked fifth in the
nation, reporting a 4% increase in non-agricultural job growth.
Along with the State's domestic boom, the economy has already seen
some benefit from the passage of the North American Free Trade
Agreement. Currently, 13%--20% of wages earned by Mexicans flows
into the United States primarily in the form of increased retail
sales. Consequently, it is estimated that the border towns in
Arizona take in about $34 million per year from such spending.
However, additional growth for Arizona and other Mexico-US border
towns is likely to rely on the improvement of services such as
transportation and utilities.

In addition, like other states, Arizona is being forced to address
and correct the disparities in the quality of education offered
throughout its many school districts. A ruling that held the State's
method of funding schools as unconstitutional was delivered by the
Arizona Supreme Court in July. Governor Symington said he welcomed
the ruling and that it represents a tremendous opportunity for the
State to come to grips with the entire tax system. The common
problem faced by most states is that a dependence on property taxes
for funding creates inevitable inequities among the districts.
Consequently, less-affluent school districts find it impossible to
issue bonds to expand or improve the quality of their services
because they do not have sufficient property valuation to back the
bonds.
<PAGE>
During the first half of the period, we maintained a relatively
defensive average portfolio maturity, concluding the month of June
in the 25-day range. This was a result of both the lack of short-
term fixed rate supply and the ever-present volatility in the
Treasury market. Additionally, in July the Fund matured $18.5
million of its fixed-rate issues and was mainly invested in variable
rate demand notes and commercial paper. We utilized commercial paper
to allow the Fund to pick up yield by extending out on the yield
curve when appropriate.

During the months of August and September, the State's
municipalities and authorities brought to market their annual
financing for cash flow purposes. This borrowing totaled $187
million and included financing for Pima and Maricopa Counties as
well as the school districts in Maricopa County. In August, we
purchased $11.5 million of Maricopa County Tax Anticipation Notes
which have a 5% coupon and mature on July 28, 1995 at a yield of
4.35%. This provided the Fund with both yield and diversification
while not compromising credit quality.

The Fund ended the period with a relatively neutral average maturity
of 59 days in response to the perception that the Federal Reserve
Board's interest rate hikes may not have been sufficient to slow
down a growing US economy. We will continue to maintain the
portfolio's average maturity in this range until a clearer picture
emerges as to the direction of interest rates.

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

Sincerely,

CMA ARIZONA MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
CMA Arizona 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.

(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) Deferred organization expenses and prepaid registration fees--
Deferred organization expenses are charged to expense on a straight-
line basis over a five-year period. Prepaid registration fees are
charged to expense as the related shares are issued.

(e) Dividends 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"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co. ("ML & Co."). The limited partners
are ML & Co. and Fund Asset Management, Inc. ("FAMI"), which is also
an indirect wholly-owned subsidiary of ML & Co.

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. For the six months ended September 30, 1994, FAM earned
fees of $194,908, of which $126,252 was voluntarily waived.

The most restrictive annual expense limitation requires that the
Adviser reimburse the Fund to the extent the Fund's expenses
(excluding interest, taxes, distribution fees, brokerage fees and
commissions, and extraordinary items) exceed in any fiscal year 2.5%
of the Fund's first $30 million of average daily net assets, 2.0% of
the Fund's next $70 million of average daily net assets, and 1.5% of
the average daily net assets in excess thereof. No fee payment will
be made to the Investment Adviser during any year which will cause
such expenses to exceed the pro rata expense limitation at the time
of such payment.

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
other directly involved branch office personnel for selling shares
of the Fund and for providing direct personal services to
shareholders. The distribution fee is not compensation for the
administrative and operational services rendered to the Fund by
MLPF&S in processing share orders and administering shareholder
accounts.

Financial Data Services, Inc. ("FDS"), 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, FAMI, PSI, MLPF&S, FDS, and/or ML & Co.
