2        SUMMARY PROSPECTUS — GOLDMAN SACHS INTERNATIONAL EQUITY ESG FUND

EXPENSE EXAMPLE

This 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 Class A, Class C, Institutional, Service, Investor, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R6 and/or Class T 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 (except that the Example incorporates the expense limitation arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Class A Shares	$	675	$	972	$	1,290	$	2,191
Class C Shares
— Assuming complete redemption at end of period	$	307	$	676	$	1,171	$	2,535
— Assuming no redemption	$	207	$	676	$	1,171	$	2,535
Institutional Shares	$	92	$	324	$	574	$	1,291
Service Shares	$	143	$	480	$	840	$	1,853
Investor Shares	$	107	$	369	$	651	$	1,456
Class R6 Shares	$	91	$	321	$	569	$	1,279
Class T Shares	$	378	$	684	$	1,012	$	1,939

PORTFOLIO TURNOVER

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended October 31, 2017 was 116% of the average value of its portfolio.

PRINCIPAL STRATEGY

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a diversified portfolio of equity investments of non-U.S. issuers that the Investment Adviser believes adhere to the Fund’s environmental, social and governance (“ESG”) criteria. Such equity investments may include exchange-traded funds (“ETFs”), futures and other instruments with similar economic exposures. The Fund intends to have investments economically tied to at least three countries, not including the United States, and may invest in the securities of issuers in emerging market countries.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 30-50 companies that are considered by the Investment Adviser to be positioned for long-term capital appreciation. The Investment Adviser uses a quantitative and qualitative process to identify, at the time of investment, issuers that satisfy the Fund’s ESG criteria. The Investment Adviser evaluates company ESG performance based on fundamental, proprietary research using internal and external data sources as well as engagement with company management.

The Investment Adviser analyzes individual companies, incorporating the Fund’s ESG criteria as part of a fundamental, bottom-up financial analysis. The Investment Adviser conducts an analysis of the issuer’s corporate governance factors and a range of environmental and social factors that may vary by sector, alongside traditional fundamental metrics. The Investment Adviser engages in active dialogues with company management teams to further inform investment decision-making and to foster best corporate governance practices using its fundamental and ESG analysis.

The Investment Adviser’s process begins with an investment universe comprising the stocks held in the MSCI EAFE Index and its own research coverage. The Investment Adviser then seeks to avoid what the Investment Adviser believes to be structurally unattractive market segments, industries that do not meet the Fund’s ESG criteria, and particular companies with weak corporate governance that are involved in, and/or derive significant revenue from, certain industries or product lines, including:

◾ gambling,

◾ adult entertainment,

◾ alcohol,

◾ tobacco,

◾ coal, and

◾ weapons

Finally, the Investment Adviser selects a portfolio of stocks based on its research, proprietary valuation, ESG analysis, and dialogues with company management.

The Investment Adviser may sell holdings for several reasons, including, among others, changes in a company’s fundamentals or earnings, a company no longer meeting the Fund’s ESG criteria, or a company otherwise failing to conform to the Investment Adviser’s investment philosophy.

The Fund expects to invest a substantial portion of its assets in the securities of issuers located in the developed countries of Western Europe and in Japan, but may also invest in securities of issuers located in emerging countries. From time to time, the Fund’s investments in a particular developed country may exceed 25% of its investment portfolio.

The Fund may also invest up to 20% of its Net Assets in equity investments that may not adhere to the Fund’s ESG criteria and in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Index (Net, USD, Unhedged).

3        SUMMARY PROSPECTUS — GOLDMAN SACHS INTERNATIONAL EQUITY ESG FUND

PRINCIPAL RISKS OF THE FUND

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

ESG Standards Risk. The Fund’s adherence to its ESG standards when selecting investments may affect the Fund’s exposure to certain companies, sectors, regions, and countries and may affect the Fund’s performance depending on whether such investments are in or out of favor. Adhering to the ESG standards may also affect the Fund’s performance relative to similar funds that do not adhere to such standards. Additionally, identifying and selecting equity investments in non-U.S. issuers that adhere to the ESG standards often require subjective analysis and may be relatively more difficult than applying the ESG standards to equity investments of all issuers. Certain investments may be dependent on U.S. and foreign government policies, including tax incentives and subsidies. The ESG standards to which the Fund adheres may be changed without shareholder approval.

Foreign and Emerging Countries Risk. Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging countries.

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often underdeveloped and may be considerably less well regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

Issuer Concentration Risk. The Fund intends to invest in up to approximately 50 companies. This relatively small number of issuers may subject the Fund to greater risks, because a decline in the value of any single investment held by the Fund may adversely affect the Fund’s overall value more than it would affect that of a fund holding a greater number of investments.

Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Sector Risk. To the extent the Fund focuses its investments in one or more sectors (such as the financial services or telecommunications sectors), the Fund will be subject, to a greater extent than if its investments were diversified across different sectors, to the risks of volatile economic cycles and/or conditions and developments that may be particular to that sector, such as: adverse economic, business, political, environmental or other developments.

Stock Risk. Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

PERFORMANCE

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R6 and Class T Shares compare to those of a broad-based securities market index. Through February 27, 2018, the Fund had been known as the Goldman Sachs Focused International Equity Fund, and certain of its strategies differed. Performance information set forth below reflects the Fund’s former strategies prior to that date. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

* Class R6 Shares commenced operations on February 26, 2016. Prior to that date, performance of the Class R6 Shares shown in the table above is that of the Institutional Shares. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

** As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares 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 an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

5        SUMMARY PROSPECTUS — GOLDMAN SACHS INTERNATIONAL EQUITY ESG FUND

PORTFOLIO MANAGEMENT

Goldman Sachs Asset Management, L.P. is the investment adviser for the Fund (the “Investment Adviser” or “GSAM”).

Portfolio Managers: Suneil Mahindru, Managing Director, Chief Investment Officer of International Equity, has managed the Fund since 2014; and Alexis Deladerrière, CFA, Managing Director, has managed the Fund since 2012.

BUYING AND SELLING FUND SHARES

The minimum initial investment for Class A and Class C Shares is, generally, $1,000. The minimum initial investment for Institutional Shares is, generally, $1,000,000 for individual or certain institutional investors, alone or in combination with other assets under the management of the Investment Adviser and its affiliates. There is no minimum for initial purchases of Investor, Class R6 and Class T Shares, except for certain institutional investors who purchase Class R6 Shares directly with the Fund’s transfer agent for which the minimum initial investment is $5,000,000. Those share classes with a minimum initial investment requirement do not impose it on certain employee benefit plans, and Institutional Shares do not impose it on certain investment advisers investing on behalf of other accounts.

The minimum subsequent investment for Class A and Class C shareholders is $50, except for certain employee benefit plans, for which there is no minimum. There is no minimum subsequent investment for Institutional, Investor, Class R6 or Class T shareholders.

The Fund does not impose minimum purchase requirements for initial or subsequent investments in Service Shares, although an Intermediary (as defined below) may impose such minimums and/or establish other requirements such as a minimum account balance.

You may purchase and redeem (sell) shares of the Fund on any business day through certain intermediaries that have a relationship with Goldman Sachs & Co. LLC (“Goldman Sachs”), including banks, trust companies, brokers, registered investment advisers and other financial institutions (“Intermediaries”).

TAX INFORMATION

The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Investments through tax-deferred arrangements may become taxable upon withdrawal from such arrangements.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through an Intermediary, the Fund and/ or its related companies may pay the Intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your Intermediary’s website for more information.
