Example

The Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The one-year example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the fee waiver and expense limitation agreement by The Dreyfus Corporation. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - Class A, C, I, & Y Prospectus - Dreyfus Emerging Markets Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	766	1,206	1,670	2,949
Class C	378	884	1,515	3,213
Class I	178	553	953	2,072
Class Y	171	530	913	1,987

You would pay the following expenses if you did not redeem your shares:

Expense Example No Redemption - Class A, C, I, & Y Prospectus - Dreyfus Emerging Markets Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	766	1,206	1,670	2,949
Class C	278	884	1,515	3,213
Class I	178	553	953	2,072
Class Y	171	530	913	1,987

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 80.11% of the average value of its portfolio.

Principal Investment Strategy

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in the stocks of companies organized, or with a majority of assets or business, in emerging market countries. In selecting stocks, the portfolio managers identify potential investments through extensive quantitative and fundamental research using a value-oriented, research-driven approach. Emphasizing individual stock selection rather than economic and industry trends, the fund focuses on value, business health and business momentum. The fund considers emerging market countries to be generally all countries represented by the Morgan Stanley Capital International (MSCI) Emerging Markets Index.

Principal Risks

An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

·Foreign investment risk. To the extent the fund invests in foreign securities, the fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund. To the extent the fund's investments are focused in a limited number of foreign countries, the fund's performance could be more volatile than that of more geographically diversified funds.

·Emerging market risk. The securities of issuers located or doing substantial business in emerging market countries tend to be more volatile and less liquid than the securities of issuers located in countries with more mature economies. Emerging markets generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. Investments in these countries may be subject to political, economic, legal, market and currency risks. The risks may include less protection of property rights and uncertain political and economic policies, the imposition of capital controls and/or foreign investment limitations by a country, nationalization of businesses and the imposition of sanctions by other countries, such as the United States.

From time to time, the fund's investments may be concentrated in issuers located in China and, therefore, at such times, the fund may be particularly exposed to the economy, industries, securities and currency markets of China, which may be adversely affected by protectionist trade policies, slow economic activity in other Asian countries or worldwide, political and social instability, environmental events and natural disasters, regional and global conflicts, terrorism and war, include actions that are contrary to the interests of the United States.

·Foreign currency risk. Investments in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Currency exchange rates may fluctuate significantly over short periods of time. Foreign currencies are also subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government intervention and controls.

·Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general market conditions or because of factors that affect the particular company or the company's industry.

·Liquidity risk. When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. Investments that are illiquid or that trade in lower volumes may be more difficult to value. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities.

·Non-diversification risk. The fund is non-diversified, which means that the fund may invest a relatively high percentage of its assets in a limited number of issuers. Therefore, the fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Performance

The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Class A shares from year to year. Sales charges, if any, are not reflected in the bar chart, and if those charges were included, returns would have been less than those shown. The table compares the average annual total returns of the fund's shares to those of a broad measure of market performance. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. More recent performance information may be available at www.dreyfus.com.

Year-by-Year Total Returns as of 12/31 each year (%) Class A

	Best Quarter Q2, 2009: 36.58% Worst Quarter Q4, 2008: -25.48%
The year-to-date total return of the fund's Class A shares as of March 31, 2017 was 12.92%.

Average Annual Total Returns (as of 12/31/16)

After-tax performance is shown only for Class A shares. After-tax performance of the fund's other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through U.S. tax-deferred arrangements such as 401(k) plans or individual retirement accounts. Returns after taxes on distributions and sale of fund shares may be higher than returns before taxes or returns after taxes on distributions due to an assumed tax benefit from losses on a sale of the fund's shares at the end of the period.

For the fund's Class Y shares, periods prior to the inception date reflect the performance of the fund's Class A shares, not reflecting the applicable sales charges for Class A shares. Such performance figures have not been adjusted to reflect applicable class fees and expenses. Each share class is invested in the same portfolio of securities, and the annual returns would have differed only to the extent that the classes do not have the same expenses.

[1] The fund's investment adviser, The Dreyfus Corporation, has contractually agreed, until October 1, 2017, to waive receipt of its fees and/or assume the direct expenses of the fund so that the expenses of none of the classes (excluding Rule 12b-1 fees, shareholder services fees, taxes, interest, brokerage commissions, commitment fees on borrowings and extraordinary expenses) exceed 1.75%. On or after October 1, 2017, The Dreyfus Corporation may terminate this expense limitation at any time.
