Risk/Return [Heading]	rr_RiskReturnHeading	Goldman Sachs Blue Chip Fund—Summary
Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Goldman Sachs Blue Chip Fund (formerly Goldman Sachs Dynamic U.S. Equity Fund) (the “Fund”) seeks long-term growth of capital.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you invest at least $50,000 in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 46 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 86 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	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 August 31, 2017 was 77% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	77.00%
Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.
Expense Breakpoint Discounts [Text]	rr_ExpenseBreakpointDiscounts	You may qualify for sales charge discounts on purchases of Class A Shares if you invest at least $50,000 in Goldman Sachs Funds.

Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R and/or Class R6 Shares at the end of those periods, unless otherwise stated. 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 fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	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 “blue chip” companies. Blue chip companies are companies that, in the Investment Adviser’s view, enjoy characteristics that include strong market positions, seasoned management teams, solid financial fundamentals and high-quality reputations. Although blue chip companies generally have large or medium market capitalizations, the Investment Adviser may invest in companies that it believes have good, long-term prospects to become well-known, established or blue chip companies. The Fund may also invest up to 20% of its Net Assets in foreign securities. The Fund’s portfolio managers combine ideas from the Goldman Sachs Asset Management Growth and Value Teams to provide broad U.S. equity market exposure using securities of “blue chip” companies of any investment style. The Goldman Sachs Asset Management Growth Team uses fundamental research to identify strong business franchises with favorable long-term growth prospects, excellent management and high-quality reputations. Investment criteria include dominant market share, positive free cash flow, enduring competitive advantages and sustainable growth. The process also includes a valuation component. The Goldman Sachs Asset Management Value Team’s philosophy is based on the belief that all successful investing should thoughtfully weigh two important attributes of a stock: price and prospects. The team uses a strong valuation discipline to purchase well-positioned, cash-generating businesses run by shareholder-oriented management teams. The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may also, but does not currently intend to, invest in fixed income securities, including government, corporate and bank debt obligations. The Fund’s benchmark index is the S&P 500® Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Foreign 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, 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. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. 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. 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.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	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, Investor, Class R and Class R6 Shares compare to those of a broad-based securities market index. Between May 1, 2015 through October 31, 2017, the Fund had been known as the Goldman Sachs Dynamic U.S. Equity Fund and, since the Fund’s inception through April 30, 2015, the Fund had been known as the Goldman Sachs U.S. Equity Fund, and certain of its principal investment strategies differed. Performance information set forth below prior to October 31, 2017 reflects the performance resulting from the Fund’s former strategies. 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.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.084% of the Fund’s average daily net assets. Additionally, Goldman Sachs & Co. LLC (“Goldman Sachs”), the Fund’s transfer agent, has agreed to waive a portion of its transfer agency fee (a component of “Other Expenses”) equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, and Class R Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[5] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. 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.
