The Tikvah Fund (Hebrew: קרן תקווה, meaning 'hope') is a U.S.-based American Jewish philanthropic foundation and politically conservative nonprofit charitable organization founded in 1992 by financier Zalman Chaim Bernstein, who also founded Sanford C. Bernstein and Company. Its stated mission is to promote Jewish thought and ideas, with a focus on Jewish excellence, Zionism, Western civilization, and support for Jewish and conservative causes including education, research, and advocacy aligned with Israeli and Jewish nationalist interests. The organization maintains close ties to conservative movements in the U.S. and Israel, and its faculty includes multiple neoconservative policy veterans.

Under the leadership of CEO Eric Cohen since 2007, Tikvah has grown into one of American Jewry's most prominent conservative think tanks and educational organizations, operating programs in both the United States and Israel. Its U.S. program budget grew from approximately $19.3 million in 2024 to $24.5 million in 2025, prior to receiving a landmark $10.4 million grant from the National Endowment for the Humanities (NEH) in 2025, the largest in the agency’s 60-year history, awarded for its "Jewish Civilization Project" aimed at combating antisemitism. This grant was controversial due to Tikvah reportedly being specially invited to apply, while the NEH had cancelled over 1,000 other grants including several Jewish studies programs, leading to criticism of political favoritism. As of 2011, the fund held assets worth over $162 million.

Tikvah operates an extensive network of educational programs, publications, fellowships, and institutional partnerships. It funds educational programs such as Emet Classical Academy, a Jewish classical school for 5th through 12th graders in Manhattan, intensive fellowships including the Charles Krauthammer Fellowship for aspiring writers and policy analysts, summer institutes, the Tikvah Scholars Program, the Lobel Center for Jewish Classical Education, and the Millstone Scholars program. Its media ventures include Mosaic Magazine, the Jewish Review of Books, the Tikvah Podcast network, and online courses available through Tikvah Online Academy.

In Israel, Tikvah operates through its sister organization, Tikvah Fund Israel, which publishes the Hebrew-language quarterly Hashiloach, organizes the annual Israeli Conservatism Conference launched in 2019, and maintains close ties with the Kohelet Policy Forum. Tikvah also founded the Israel Law and Liberty Forum in 2020, modeled on the American Federalist Society, focusing on promoting judicial restraint in Israel. The organization further hosts the annual Jewish Leadership Conference in New York, featuring prominent speakers such as Mike Pompeo, Ron DeSantis, Ben Shapiro, and Bari Weiss.

Tikvah has been a significant subject of controversy, particularly for its close relationship with the Kohelet Policy Forum, a key architect of the Netanyahu government's 2023 judicial overhaul effort. This association led Israeli protesters to target Tikvah’s New York offices in 2023, and 25 Tikvah alumni publicly urged the organization to sever ties with Kohelet.
