Welcome to the MacArthur Foundation Grants Portal

The John D. and Catherine T. MacArthur Foundation supports creative people and effective institutions committed to building a more just, verdant, and peaceful world. In addition to selecting the MacArthur Fellows, the Foundation works to defend human rights, advance global conservation and security, make cities better places, and understand how technology is affecting children and society.

MacArthur develops grantmaking strategies designed to meet very specific goals. We encourage you to closely read information about each program to determine whether your project falls within MacArthur’s grantmaking guidelines. Please note that the Foundation awards the majority of its 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 the MacArthur Foundation visit our web site, at www.macfound.org, read our FAQs, view our annual report, and review the application guidelines for the areas of work for which you are interested in applying.
