MuniYield Quality Fund II, Inc.

TO OUR SHAREHOLDERS

For the six months ended April 30, 1999, the Common Stock of MuniYield Quality
Fund II, Inc. earned $0.433 per share income dividends, which included earned
and unpaid dividends of $0.066. This represents a net annualized yield of 5.99%,
based on a month-end per share net asset value of $14.58. Over the same period,
the total investment return on the Fund's Common Stock was +0.03%, based on a
change in per share net asset value from $15.52 to $14.58, and assuming
reinvestment of $0.723 per share ordinary income dividends and $0.213 per share
capital gains distributions.

For the six months ended April 30, 1999, the Fund's Auction Market Preferred
Stock had an average yield as follows: Series A, 4.22%; Series B, 4.21%; and
Series C, 3.81%.

The Municipal Market Environment

During the six months ended April 30, 1999, long-term bond yields generally
moved higher. From November 1998 through mid-January 1999, long-term bond yields
traded in a relatively narrow range. However, during February, a number of
economic indicators were released that suggested that economic growth in the
United States would likely remain strong throughout most of 1999. Consequently,
long-term US Treasury bond yields rose more than 60 basis points (0.60%) to
5.70% by early March. During the remainder of the six-month period, US Treasury
bond yields traded between 5.50% and 5.70% as the lack of inflationary pressures
offset much of the concerns generated by continued strong economic growth.
During most of the period, long-term, uninsured tax-exempt bond yields exhibited
far less volatility and were largely stable. Also, long-term municipal bond
yields rose just 5 basis points to 5.29% at the end of April 1999, as measured
by the Bond Buyer Revenue Bond Index.

In recent months, the tax-exempt market was better able to withstand much of the
upward pressure on bond yields because of its stronger technical position. While
the continued positive inflationary environment limited some of the recent
increases in taxable bond yields, a deteriorating supply/demand position helped
push taxable bond yields significantly higher than municipal bond yields. Much
of the US Treasury bond market's underperformance in recent months can be
attributed to the large amounts of taxable corporate issuance. Large taxable
corporate underwritings reduced the demand for US Government securities in
recent months, pushing US Treasury bond yields higher.

On the other hand, the tax-exempt bond market enjoyed only limited new-issue
supply. During the six months ended April 30, 1999, more than $123 billion in
new long-term tax-exempt securities was underwritten, a decline of 10% compared
to the same period a year ago. Municipalities issued less than $60 billion in
long-term tax-exempt securities during the three months ended April 30, 1999, a
decline of 25% compared to the April 30, 1998 quarter. More recently, the rate
of new tax-exempt issuance has declined even further. During April 1999, just
over $15 billion in long-term tax-exempt securities was marketed, a decline of
over 33% compared to April 1998 levels. As municipal bond yields fell and
stabilized in recent quarters, the ability of municipalities to refinance
existing higher-couponed debt declined. This led to a significant decrease in
refunding issuance and an overall drop in new municipal bond supply. When
coupled with ongoing, moderate retail and institutional demand, the tax-exempt
bond market was able to avoid much of the yield volatility exhibited by US
Treasury securities.

Looking ahead, the expected combination of moderate economic growth in the
United States and continued negligible inflation suggests a relatively stable
interest rate environment. However, in recent years, bond yields reached their
annual peaks in early May and declined for the remainder of the year. A
meaningful decline in fixed-income bond yields would require either evidence of
a significant slowdown in the US economy or the resumption of concerns regarding
renewed shocks to the world's economic


                                                                               1

system. Currently, neither condition exists or seems likely in the immediate
future. In our opinion, this suggests a continuation of the narrow trading
ranges seen in recent months.

Portfolio Strategy

During the last several months, we adopted a more neutral investment strategy,
since indicators pointed to a continuation of healthy domestic economic growth
and benign inflation. In addition, we believed that long-term tax-exempt bond
yields would continue to trade in a relatively narrow range, centered around
present levels. Consequently, we focused on income-producing securities rather
than those issues with the potential for capital gains. Should the tax-exempt
bond market perform as expected, coupon income will be the more important
component of the Fund's performance. MuniYield Quality Fund II, Inc. remained
fully invested for most of the past several months. We expect to maintain this
position going forward in order to seek to enhance shareholder income.

Short-term tax-exempt yields exhibited considerable volatility in recent months.
Interest rates paid to the Fund's Preferred Stock shareholders traded below 3%
in December 1998, reflecting heightened investor demand at year-end. Current
short-term interest rate levels reflect tax season-related pressures, which we
expect to abate soon. During the six-month period ended April 30, 1999,
leveraging generated a significant incremental yield to the Fund's Common Stock
shareholders. Because we believe that the Federal Reserve Board's monetary
policy is likely to remain in a narrow range for the remainder of the year, we
expect short-term tax-exempt interest rates to remain at, or slightly below,
current levels. However, should the spread between short-term and long-term
interest rates narrow, the benefits of the leverage will decline and, as a
result, reduce the yield to the Fund's Common Stock. (For a complete explanation
of the benefits and risks of leveraging, see page 4 of this report to
shareholders.)

We appreciate your ongoing interest in MuniYield Quality Fund II, Inc., and we
look forward to serving your investment needs in the months and years ahead.

Sincerely,

MANAGED DIVIDEND POLICY

The Fund's dividend policy is to distribute substantially all of its net
investment income to its share holders on a monthly basis. However, in order to
provide shareholders with a more consistent yield to the current trading price
of shares of Common Stock of the Fund, the Fund may at times pay out less than
the entire amount of net investment income earned in any particular month and
may at times in any month pay out such accumulated but undistributed income
in addition to net investment income earned in that month. As a result, the
dividends paid by the Fund for any particular month may be more or less than the
amount of net investment income earned by the Fund during such month. The Fund's
current accumulated but undistributed net investment income, if any, is
disclosed in the Statement of Assets, Liabilities and Capital, which comprises
part of the Financial Information included in this report.


                                                                               3

THE BENEFITS AND RISKS OF LEVERAGING

MuniYield Quality Fund II, Inc. utilizes leveraging to seek to enhance the yield
and net asset value of its Common Stock. However, these objectives cannot be
achieved in all interest rate environments. To leverage, the Fund issues
Preferred Stock, which pays dividends at prevailing short-term interest rates,
and invests the proceeds in long-term municipal bonds. The interest earned on
these investments is paid to Common Stock shareholders in the form of dividends,
and the value of these portfolio holdings is reflected in the per share net
asset value of the Fund's Common Stock. However, in order to benefit Common
Stock shareholders, the yield curve must be positively sloped; that is,
short-term interest rates must be lower than long-term interest rates. At the
same time, a period of generally declining interest rates will benefit Common
Stock shareholders. If either of these conditions change, then the risks of
leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value of the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed-rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

MuniYield Quality Fund II, Inc. (the "Fund") is registered under the Investment
Company Act of 1940 as a non-diversified, closed-end management investment
company. The Fund's financial statements are prepared in accordance with
generally accepted accounting principles which may require the use of management
accruals and estimates. These unaudited financial statements reflect all
adjustments which are, in the opinion of management, necessary to a fair
statement for the interim period presented. All such adjustments are of a normal
recurring nature. The Fund determines and makes available for publication the
net asset value of its Common Stock on a weekly basis. The Fund's Common Stock
is listed on the New York Stock Exchange under the symbol MQT. The following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at their fair value as determined in good faith
by or under the direction of the Board of Directors of the Fund, including
valuations furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the debt markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

o Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Options--The Fund is authorized to write covered call options and purchase put
options. When the Fund writes an option, an amount equal to the premium received
by the Fund is reflected as an asset and an equivalent liability. The amount of
the liability is subsequently marked to market to reflect the current market
value of the option written. When a security is purchased or sold through an
exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from (or added to)
the proceeds of the security sold. When an option expires (or the Fund enters
into a closing transaction), the Fund realizes a gain or loss on the option to
the extent of the premiums received or paid (or gain or loss to the extent the
cost of the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) 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.


                                                                              13

NOTES TO FINANCIAL STATEMENTS (concluded)

(d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

(e) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

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 at
an annual rate of 0.50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Stock.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

- --------------------------------------------------------------------------------

As of April 30, 1999, net unrealized appreciation for Federal income tax
purposes aggregated $9,435,640, of which $15,790,647 related to appreciated
securities and $6,355,007 related to depreciated securities. The aggregate cost
of investments at April 30, 1999 for Federal income tax purposes was
$487,718,364.

4. Capital Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of capital stock, including
Preferred Stock, par value $.10 per share, all of which were initially
classified as Common Stock. The Board of Directors is authorized, however, to
reclassify any unissued shares of capital stock without approval of the holders
of Common Stock.

Common Stock

Shares issued and outstanding during the six months ended April 30, 1999
increased by 296,045 as a result of dividend reinvestment and during the year
ended October 31, 1998 remained constant.

Preferred Stock

Auction Market Preferred Stock ("AMPS") are shares of Preferred Stock of the
Fund, with a par value of $.05 per share and a liquidation preference of $25,000
per share, that entitle their holders to receive cash dividends at an annual
rate that may vary for the successive dividend periods. The yields in effect at
April 30, 1999 were as follows: Series A, 3.35%; Series B, 3.35%; and Series C,
3.40%.

Shares issued and outstanding during the six months ended April 30, 1999 and the
year ended October 31, 1998 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from 0.25% to 0.375%, calculated on the proceeds of
each auction. For the six months ended April 30, 1999, Merrill Lynch, Pierce,
Fenner & Smith Incorporated, an affiliate of FAM, earned $56,221 as commissions.

5. Subsequent Event:

On May 6, 1999, the Fund's Board of Directors declared an ordinary income
dividend to Common Stock shareholders in the amount of $.066113 per share,
payable on May 27, 1999 to shareholders of record as of May 21, 1999.

YEAR 2000 ISSUES

Many computer systems were designed using only two digits to designate years.
These systems may not be able to distinguish the Year 2000 from the Year 1900
(commonly known as the "Year 2000 Problem"). The Fund could be adversely
affected if the computer systems used by the Fund's management or other Fund
service providers do not properly address this problem before January 1, 2000.
The Fund's management expects to have addressed this problem before then, and
does not anticipate that the services it provides will be adversely affected.
The Fund's other service providers have told the Fund's management that they
also expect to resolve the Year 2000 Problem, and the Fund's management will
continue to monitor the situation as the Year 2000 approaches. However, if the
problem has not been fully addressed, the Fund could be negatively affected. The
Year 2000 Problem could also have a negative impact on the securities in which
the Fund invests and this could hurt the Fund's investment returns.

This report, including the financial information herein, is transmitted to the
shareholders of MuniYield Quality Fund II, Inc. for their information. It is not
a prospectus, circular or representation intended for use in the purchase of
shares of the Fund or any securities mentioned in the report. Past performance
results shown in this report should not be considered a representation of future
performance. The Fund has leveraged its Common Stock by issuing Preferred Stock
to provide the Common Stock shareholders with a potentially higher rate of
return. Leverage creates risks for Common Stock shareholders, including the
likelihood of greater volatility of net asset value and market price of shares
of the Common Stock, and the risk that fluctuations in the short-term dividend
rates of the Preferred Stock may affect the yield to Common Stock shareholders.
