The Paipai (Pai pai, Pa’ipai, Akwa’ala, Yakakwal) are an aboriginal people of northern Baja California, Mexico. They occupied a territory lying 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 northern highlands.
