We Need Your Help

As the only accredited orangutan sanctuary in the country and one of a handful of accredited chimpanzee sanctuaries, the Center for Great Apes has been rescuing great apes for over 25 years. The Center for Great Apes does not receive funding from the federal or state governments. We are supported by donations from generous people like you, who care about the future of our orangutans and chimpanzees (both endangered species).

Center for Orangutan and Chimpanzee Conservation, Inc. dba Center for Great Apes is a 501(c)(3) nonprofit organization, FEID 65-0444725.
