The Pan African Sanctuary Alliance is the largest network of primate rescue and conservation centers on the continent of Africa working to protect Africa's primates and halt the illegal trades that endanger them. Twenty-three member sanctuaries in 13 countries rescue and rehabilitate endangered and threatened primates, protect vast tracts of habitat, and work tirelessly to reduce human threats to these species.

With a small administrative office in Portland, Oregon, USA, PASA depends on volunteers around the world to fill critical roles.
