The Paipai (Pai pai, Pa'ipai, Akwa'ala, Yakakwal) are an indigenous people of Mexico living in northern Baja California. Their traditional territory lies between the Kiliwa on the south and the Kumeyaay and Cocopa on the north, and extending from San Vicente near the Pacific coast nearly to the Colorado River's delta in the east. Today they are concentrated primarily at the multi-ethnic community of Santa Catarina in Baja California's Sierra de Juárez.
