The Aspen Institute is an international nonprofit organization founded in 1949 as the Aspen Institute for Humanistic Studies. The Institute and its international partners promote the creation of a free, just, and equitable society in a nonpartisan and nonideological setting through seminars, policy programs, conferences, and leadership development initiatives. The institute is headquartered in Washington, D.C., United States, and has campuses in Aspen, Colorado, and near the shores of the Chesapeake Bay at the Wye River in Maryland. It has partner Aspen Institutes in Berlin, Rome, Madrid, Paris, Lyon, Tokyo, New Delhi, Prague, Bucharest, Mexico City, and Kiev, as well as leadership initiatives in the United States and on the African continent, India, and Central America.
The Aspen Institute is largely funded by foundations such as the Carnegie Corporation, the Rockefeller Brothers Fund, the Gates Foundation, the Lumina Foundation, and the Ford Foundation, by seminar fees, and by individual donations. Its board of trustees includes leaders from politics, government, business and academia who also contribute to its support. A report by the Center for International Policy's Foreign Influence Transparency Initiative of the top 50 think tanks on the University of Pennsylvania's Global Go-To Think Tanks rating index found that during the period 2014-2018 the Aspen Institute received the fifth-highest amount of funding from outside the United States compared to other think tanks, with a total of more than US$8 million from donors that originated primarily in Western democracies but also "sizeable donations from undemocratic regimes in Saudi Arabia and the United Arab Emirates."
