The John D. and Catherine T. MacArthur Foundation supports creative people, effective institutions, and influential networks building a more just, verdant, and peaceful world. MacArthur is placing a few big bets that truly significant progress is possible on some of the world's most pressing social challenges, including advancing global climate solutions, promoting local justice reform, revitalizing local news in the U.S., and reducing corruption in Africa’s most populous country, Nigeria. In addition to the MacArthur Fellows Program and the global 100&Change competition, the Foundation continues its historic commitments to the role of journalism in a responsive democracy, as well as the vitality of our headquarters city, Chicago.

MacArthur is one of the largest independent foundations in the United States. Since our founding in 1978, we have supported organizations that work in 117 countries. In addition to Chicago, MacArthur has offices in India and Nigeria.

MacArthur develops grantmaking strategies designed to meet specific goals. We encourage you to closely read information about each program to determine whether your project falls within our grantmaking guidelines. Please note that we award the majority of our grants to organizations identified by our Staff. Each year we also award grants to individuals through the MacArthur Fellows program, which does not accept applications or nominations. To learn more about MacArthur visit our web site, at www.macfound.org, read our FAQs, and review the grant guidelines for the areas of work most aligned with your organization.
