Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Goldman Sachs Global Core Fixed Income Fund (the “Fund”) seeks a total return consisting of capital appreciation and income.
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. The table does not take into account brokerage commissions that you may pay on your purchases and sales of Institutional Shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you invest at least $100,000 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 63 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 127 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-158 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, 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 March 31, 2020 was 610% of the average value of its portfolio.

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. The Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor 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). The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Institutional Shares of the Fund. 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 portfolio of fixed income securities of U.S. and foreign issuers. Foreign securities include securities of issuers located outside the U.S. or securities quoted or denominated in a currency other than the U.S. dollar. The Fund also enters into transactions in foreign currencies, typically through the use of forward contracts and swap contracts. The Fund may also engage in forward foreign currency transactions for both hedging and non-hedging purposes. The Fund also intends to invest in derivatives, including (but not limited to) forwards, interest rate futures, interest rate swaps and credit default swaps, which are used primarily to hedge the Fund’s portfolio risks, manage the Fund’s duration and/or gain exposure to certain fixed income securities or indices. Under normal market conditions, the Fund will: Have at least 30% of its Net Assets, after considering the effect of currency positions, denominated in U.S. dollars Have investments economically tied to at least three countries, including the United States Seek to meet its investment objective by pursuing investment opportunities in foreign and domestic fixed income securities markets and by engaging in currency transactions to seek to enhance returns and to seek to hedge its portfolio against currency exchange rate fluctuations The Fund may invest more than 25% of its total assets in the securities of corporate and governmental issuers economically tied to each of Canada, Germany, Japan and the United Kingdom as well as in the securities of U.S. issuers. Not more than 25% of the Fund’s total assets will be invested in securities of issuers in any other single foreign country. The Fund may also invest in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (“emerging countries debt”) up to the weight of emerging countries debt in the Fund’s benchmark index plus 10% of its total assets measured at the time of purchase (“Total Assets”). The fixed income securities in which the Fund may invest include: Securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored enterprises (“U.S. Government Securities”), including agency issued adjustable rate and fixed rate mortgage-backed securities or other mortgage-related securities (“Agency Mortgage-Backed Securities”), and custodial receipts therefor Securities issued or guaranteed by a foreign government or any of its political subdivisions, authorities, agencies, instrumentalities or by supranational entities Corporate debt securities Certificates of deposit and bankers’ acceptances issued or guaranteed by, or time deposits maintained at, U.S. or foreign banks (and their branches wherever located) having total assets of more than $1 billion Commercial paper Privately issued adjustable rate and fixed rate mortgage-backed securities or other mortgage-related securities (“Private Mortgage-Backed Securities” and, together with Agency Mortgage-Backed Securities, “Mortgage-Backed Securities”) and asset-backed securities The Fund may gain exposure to Agency Mortgage-Backed Securities through several methods, including by utilizing to-be-announced (“TBA”) agreements in Agency Mortgage-Backed Securities or through the use of reverse repurchase agreements. TBA agreements for Agency Mortgage-Backed Securities are standardized contracts for future delivery of fixed-rate mortgage pass-through securities in which the exact mortgage pools to be delivered are not specified until shortly before settlement. A reverse repurchase agreement enables the Fund to gain exposure to specified pools of Agency Mortgage-Backed Securities by purchasing them on a forward settling basis and using the proceeds of the reverse repurchase agreement to settle the trade. The Fund may also seek to obtain exposure to fixed income investments through investments in affiliated or unaffiliated investment companies, including exchange-traded funds (“ETFs”). The Fund may invest in fixed income securities rated at least BBB– or Baa3 at the time of purchase, and at least 25% of the Fund’s Total Assets will be invested in fixed income securities rated at least AAA or Aaa at the time of purchase. Securities will either be rated by a nationally recognized statistical rating organization (“NRSRO”) or, if unrated, determined by the Investment Adviser to be of comparable credit quality. The Fund’s target duration range under normal interest rate conditions is expected to approximate that of the Bloomberg Barclays Global Aggregate Bond (Gross, USD, Hedged) Index, plus or minus 2.5 years, and over the last five years ended June 30, 2020, the duration of the index has ranged between 6.10 and 7.20 years. “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 years will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price. Subject to the above, there are no limits on the length of remaining maturities of securities held by the Fund. The approximate interest rate sensitivity of the Fund is generally comparable to that of a 6 year bond. “Core” in the Fund’s name means that the Fund focuses its investments in intermediate and long-term investment grade bonds. The Investment Adviser employs a dynamic fundamental investment process that integrates traditional fundamental factors with environmental, social and governance (“ESG”) factors. No one factor or consideration is determinative in the fundamental investment process. The Fund seeks a return in excess of its benchmark index, the Bloomberg Barclays Global Aggregate Bond Index. THE FUND IS “NON-DIVERSIFIED” UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (THE “INVESTMENT COMPANY ACT”), AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED MUTUAL FUNDS.
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. The Fund’s principal risks are presented below in alphabetical order, and not in the order of importance or potential exposure. Credit/Default Risk.  An issuer or guarantor of fixed income securities or instruments held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). Derivatives Risk.  The Fund’s use of forwards, interest rate futures, interest rate swaps, credit default swaps and other derivative instruments may result in losses. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other instruments, may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of underlying instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. 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, less stringent investor protections and disclosure standards and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls (including repatriation restrictions), 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. Interest Rate Risk.  When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments. Fluctuations in interest rates may also affect the yield and liquidity of fixed income securities and instruments held by the Fund. 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, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s 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 or otherwise maintains 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. Events such as war, acts of terrorism, social unrest, natural disasters, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments. Mortgage-Backed and Other Asset-Backed Securities Risk.  Mortgage-related and other asset-backed securities are subject to certain additional risks, including “extension risk” (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and “prepayment risk” (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk. The Fund may gain exposure to Agency Mortgage-Backed Securities by utilizing TBA agreements. TBA agreements involve the risk that the other party to the transaction will not meet its obligation. If this occurs, the Fund could lose the opportunity to obtain a price or yield that it considers advantageous. In such circumstances, the Fund may not be able to secure an alternative investment with comparable terms. TBA agreements may give rise to a form of leverage. The Fund’s use of TBA agreements may also result in a higher portfolio turnover rate and/or increased capital gains for the Fund. Non-Diversification Risk.  The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in fewer issuers than diversified mutual funds. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments. Other Investment Companies Risk.  By investing in other investment companies (including ETFs) indirectly through the Fund, investors will incur a proportionate share of the expenses of the other investment companies held by the Fund (including operating costs and investment management fees) in addition to the fees regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investment companies in direct proportion to the amount of assets the Fund invests therein. Portfolio Turnover Rate Risk.  A high rate of portfolio turnover may involve correspondingly greater expenses which must be borne by the Fund and its shareholders, and also may result in short-term capital gains taxable to shareholders. Reverse Repurchase Agreements Risk.  Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all. Sovereign Default Risk.  The issuer of the non-U.S. sovereign debt held by the Fund or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay the principal or interest when due. This may result from political or social factors, the general economic environment of a country or levels of foreign debt or foreign currency exchange rates. U.S. Government Securities Risk.  The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. It is possible that issuers of U.S. Government Securities will not have the funds to meet their payment obligations in the future.

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

[2] The “Other Expenses” for Class A, Class C, and Investor Shares have been restated to reflect expenses expected to be incurred during the current fiscal year.

[3] The “Total Annual Fund Operating Expenses” and “Total Annual Fund Operating Expenses After Fee Waiver and Expense Limitation” do not correlate to the ratios of net and total expenses to average net assets provided in the Financial Highlights, which reflect the operating expenses of the Fund and do not include “Acquired Fund Fees and Expenses.”

[4] The Investment Adviser has agreed to (i) waive a portion of its management fee equal to 0.01% of the Fund’s average daily net assets and (ii) reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service and shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% 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 0.02% as an annual percentage of the average daily net assets attributable to Class A, Class C and Investor Shares. These arrangements will remain in effect through at least July 29, 2021, and prior to such date the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[5] After Fee Waiver and Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of Class R6 Shares shown in the table above is that of 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.
