TO OUR SHAREHOLDERS:

For the six-month period ended September 30, 1997, CMA Ohio Municipal 
Money Fund paid shareholders a net annualized yield of 3.15%*. As of 
September 30, 1997, the Fund's 7-day yield was 3.33%.

Economic Environment and Investment Strategy
The state of Ohio's economy continued to experience an easing in 
economic growth during the six-month period ended September 30, 1997. 
Ohio's economy, which once acted as a catalyst for the rest of the 
nation, is currently expanding at less than 1% year over year. 
Contributing to this slowing in economic activity are the tight labor 
conditions which have existed in the state for some time. With 
seasonally adjusted unemployment levels in the 4% range, employers are 
crossing the border looking for excess capacity elsewhere while at the 
same time continuing capital improvement investments on existing 
facilities. In addition, despite high consumer confidence, the state's 
personal income levels have lagged the nation's since the end of 1995.

On March 31, 1997, the state ended its fiscal year on a positive note as 
a combination of higher-than-expected revenues and lower-than-expected 
spending led to an unobligated fund balance of $839.9 million in the 
general revenue fund. Tax revenues finished fiscal year 1997 at $334.3 
million, or 2.5% above estimates and 1.7% above the 1996 fiscal year. At 
the same time, the general revenue fund's disbursements were $722.3 
million below estimates as the state experienced a reduction in spending 
for human services programs, such as Medicaid and other welfare 
services. In the current economic climate, the state continues to fair 
well. Total revenues for the first three months of fiscal year 1998 were 
$3.8 billion, or 4.4% above the comparable period last year. These 
positive results continue to allow the state to avoid borrowing in the 
short-term municipal market to finance daily operations. In addition, 
these results continue to allow the various Ohio municipalities to 
maintain moderate borrowing levels at $659 million for the six-month 
period ended September 30, 1997. Finally, the Ohio legislature continues 
to wrestle with a proposed school funding reform bill and how to account 
for the distribution of funds. The $1.1 billion in funding for this bill 
remains uncertain as legislative conflicts appear to make the passage of 
a 1% increase in the state sales tax unlikely.

As discussed in our March 31, 1997 letter to shareholders, CMA Ohio 
Municipal Money Fund had adopted a defensive approach to the market. In 
April, we allowed the Fund's average life to decline to the 35-day range 
as we prepared to meet tax-related redemptions by replacing maturing 
short-term municipal notes with variable rate demand notes (VRDNs). This 
strategy benefited the Fund as the seasonal effect of low subscriptions 
and high redemptions, combined with a large inventory of dealer-held 
VRDNs, contributed to attractive VRDN yields. 

In May and June, supply imbalances were no different than in April. With 
a mixture of economic data and an uncertain Federal Reserve Board (FRB) 
position, there was little incentive to participate in the fixed-rate 
note market, other than for diversification purposes. During the first 
three months of the period ended September 30, 1997, we selectively 
purchased six-month municipal notes for diversification purposes as 
yields on one-year municipal notes were only marginally higher. In July, 
larger money fund subscriptions combined with large corporate demand 
allowed the municipal yield curve to shift as VRDN yields fell below 
municipal note and commercial paper levels. In addition, despite 
continued economic strength, inflationary data remained subdued, and the 
FRB remained on the sidelines. This combination of factors gave 
investors renewed confidence, which allowed the Treasury market to rally 
and interest rates in the six-month and one-year sectors to fall 
approximately 20 basis points and 45 basis points (0.25% and 0.45%), 
respectively. This rally in the Treasury market forced municipal market 
investors to scramble to extend their average life as yields on one-year 
notes declined approximately 10 basis points -- 15 basis points. We 
changed our strategy to a more neutral approach by selectively 
purchasing longer-dated municipal notes and increasing the average 
portfolio maturity to the 60-day range. 

Looking ahead, we expect to continue to maintain a neutral strategy, 
selectively participating in the longer-dated municipal note market. 
Despite the FRB's reluctance to change monetary policy thus far and 
inconclusive economic data, we will proceed cautiously as employment 
reports continue to suggest that tight labor conditions exist. These 
tight labor conditions combined with the potential of increased economic 
activity created from low interest rates could ultimately pose an 
inflationary threat and force the FRB to increase interest rates. We 
will continue to monitor and adjust our market strategy as economic 
conditions change. However, we continue to expect that Ohio's strong 
economic performance will reduce short-term note issuance. We continue 
to closely monitor credit quality while seeking an attractive tax-exempt 
yield for our shareholders.

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

CMA Ohio Municipal Money Fund
Notes to Financial Statements

1. Significant Accounting Policies:
CMA Ohio 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 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 $32,000, of which $23,000 expires in 2000, $5,000 expires 
in 2001 and $4,000 expires in 2002. This amount will be available to 
offset like amounts of any future taxable gains.
