TO OUR SHAREHOLDERS:

For the six-month period ended September 30, 1997, CMA Michigan 
Municipal Money Fund paid shareholders a net annualized yield of 
3.09%*. As of September 30, 1997, the Fund's 7-day yield was 3.24%.

Economic Environment and 
Investment Strategy
The state of Michigan's economy continued to improve during the six 
months ended September 30, 1997, benefiting from enhanced 
productivity, a competitive dollar and little increase in prices of 
goods and services. In addition, Michigan's unemployment rate for 
August fell to 3.7% as plants reopened after summer breaks and service 
and construction companies created more jobs. This seasonally adjusted 
3.7% is the lowest unemployment rate in Michigan since the Michigan 
Employment Security Agency began using seasonal adjustments in 1970. 
The state's retailers also reported an impressive rebound in July and 
August, producing some of the best numbers of the year. For example, 
52% of the state's retailers reported increased year-to-year sales for 
the month of July. According to the Michigan Retail Index, this was 
the strongest monthly showing of 1997 and a 7% increase from June's 
Index. Looking ahead, retailers' July projections for the next three 
months also rose, with 69% of retailers expecting increased sales 
during late summer and fall versus 64% in June. US automobile sales 
also rose 4.9% in August, boosted by hefty incentives from car 
dealers. Moreover, Detroit recently ranked first among US city 
exporters. During the past few years, the city has benefited 
significantly from trade flows between Mexico, Canada and the United 
States brought on by the North American Free Trade Agreement. Finally, 
the Michigan Jobs Commission announced in September that it has 
created a new unit to support the state's 11 tax-exempt Renaissance 
Zones. In June, Governor John Engler announced a compilation of 28 
projects that have already been committed to invest over $128 million 
to continue to revive these economically distressed areas.

During the six-month period ended September 30, 1997, the Federal 
Reserve Board held monetary policy steady in response to a continuing 
stream of favorable inflationary data. However, periods of strong 
consumer spending kept the US Treasury market somewhat volatile with 
the yield on the benchmark 30-year Treasury bond trading between 6.30% 
- -- 7.18%. Nonetheless, conditions affecting short-term municipal bonds 
were quite different. For a majority of the six-month period, yields 
on one-year fixed-rate notes remained in a much narrower range, 
trading between 3.80% -- 3.90%. Furthermore, during most of the period 
yields on variable rate demand obligations considerably outperformed 
those on fixed-rate issues. The factors contributing to this were an 
abundance of new variable rate products coming to market along with 
net outflows from tax-exempt money market funds. For example, during 
the first half of the six-month period, yields on variable rate 
products averaged approximately 20 basis points (0.20%) above the 
yields on one-year fixed-rate notes. Thus, when appropriate, we 
continued to increase the Fund's concentration in variable rate demand 
notes to seek to take advantage of the spread as compared to fixed-
rate notes.

As the second half of the period began, traditional fixed-rate supply 
drove up yields on short-term notes to more attractive levels versus 
their variable counterparts, providing us with a long-awaited 
opportunity to extend the Fund's maturity. We took advantage of this 
opportunity in response to the opinion that monetary policy would stay 
on hold through year-end and that yields on notes purchased during 
this time would outperform variable rate issues over the next six 
months. The Fund, which had an average portfolio maturity in the 30-
day range by early to mid-July, ended the period in the 55-day range. 
During the six-month period ended September 30, 1997, the state of 
Michigan's issuance totaled $863.3 million. Finally, 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 Michigan Municipal Money Fund, 
and we look forward to serving your investment needs in the months and 
years ahead.

CMA Michigan Municipal Money Fund
Notes to Financial Statements

1. Significant Accounting Policies:
CMA Michigan 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 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.

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. 

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 
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.

Merrill Lynch Financial Data Services, Inc. ("MLFDS"), 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, MLFDS, and/or ML & Co.

3. Shares of Beneficial Interest:
The number of shares purchased and redeemed during the period 
corresponds to the amounts included in the Statements of Changes in 
Net Assets for net proceeds from sale of shares and cost of shares 
redeemed, respectively, since shares are recorded at $1.00 per share.

4. Capital Loss Carryforward:
At March 31, 1997, the Fund had a net 
capital loss carryforward of approximately $149,000, of which $62,000 
expires in 2001, $4,000 expires in 2002, $50,000 expires in 2003 and 
$33,000 expires in 2005. This amount will be available to offset like 
amounts of any future taxable gains.
