TO OUR SHAREHOLDERS:

For the year ended March 31, 1998, CMA Michigan Municipal Money Fund
paid shareholders a net annualized yield of 3.07%.* As of March 31,
1998, the Fund's 7-day yield was 2.97%.

Economic Environment and
Investment Strategy
During the six-month period ended March 31, 1998, Michigan's
financial performance and position continued to exhibit notable
strength. This performance is a result of steady economic growth at
the state level, combined with the effects of continued expenditure
controls. The state was also able to increase its budget
stabilization fund to over $1.1 billion, a level that provides a
good foundation for Michigan's future operations. Consequently,
during January, Standard & Poor's Corp. (S&P) raised its rating on
the state's $655 million in general obligation debt to AA+ from AA.
At the same time, S&P affirmed the SP1+ rating on the state's
outstanding cash flow notes and reported that the upgrades were
based on a significant increase in state financial reserves,
improved cash flows and a significantly lower-than-expected
settlement of a lawsuit against the state for a lack of funding to
state-mandated special education programs.

During the six months ended March 31, 1998, lawmakers approved
legislation that will improve problems pertaining to the state's
seasonal cash position. As a result of state assumption of a large
portion of financing public schools, the state faced annual cash
flow weakness and dependence upon balances in its rainy day and
other common cash funds. However, this new legislation, which
restructured the timing of payments to school districts under the
state-aid formula, will alleviate short-term cash flow shortfalls
and free up the rainy day fund to meet potential future revenue
deficiencies. Other factors supporting the upgrade include steady
employment growth and a relatively low per capita debt burden. For
example, compared to a year ago, December's labor force increased by
65,000 and employment moved up by 97,000, while unemployment fell by
32,000, resulting in a year-over-year decline of 0.7% in Michigan's
unemployment rate. Most recently, the state reported its February
unemployment rate at 4.0%, still below the national rate of 4.6% for
the same period. Finally, Governor Engler signed three new tax cuts
into law by year-end, which are expected to save taxpayers more than
$110 each annually. These cuts included a $200 increase in personal
exemptions, a $600 per child deduction and an increased tuition tax
credit.

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

Throughout the fiscal year ended March 31, 1998, we maintained a
relatively neutral average portfolio maturity. We significantly
extended the Fund's average maturity only when the short-term tax-
exempt yield curve steepened. This steepening occurred at tax time
in April 1997 when cash outflows drove up yields on short-term tax-
exempt securities and, more prominently, in late summer 1997 when
states issued their annual cash flow notes. However, for most of the
fiscal year, a decrease in total fixed-rate issuance resulting from
healthy state economies and continued cash inflows kept the short-
term tax-exempt yield curve relatively flat. For example, yields on
90-day tax-exempt commercial paper performed on average with those
on short-term tax-exempt notes maturing in six months--one year for
most of the period. Thus, for a majority of that time, we used tax-
exempt commercial paper when we wanted to pursue a more aggressive
strategy.

Furthermore, during the year ended March 31, 1998, assets of tax-
exempt money market funds rose by $25.6 billion, an increase of over
17%. The Fund, which began the fiscal year in the 25-day range,
concluded the period in the 35-day range. Our strategy allowed the
Fund to perform on average relative to similar Michigan tax-exempt
money market funds for the year ended March 31, 1998. Finally, we
continue to focus on diversification and credit quality when
choosing Fund investments, and we constantly monitor the ever-
changing marketplace and adapt our investment strategy when
necessary.

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 future.

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. 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
