The Great Ape Project (GAP), founded in 1993, is an international organization of primatologists, anthropologists, ethicists, and others who advocate a United Nations Declaration of the Rights of Great Apes that would confer basic legal rights on non-human great apes: chimpanzees, gorillas and orangutans.

The rights suggested are the right to life, the protection of individual liberty, and the prohibition of torture. The organization also monitors individual great ape activity in the United States through a census program. Once rights are established, GAP would demand the release of great apes from captivity; currently 3,100 are held in the U.S., including 1,280 in biomedical research facilities.
