The Tohono O’odham (/toʊˈhɑːnə ˈɑːtʊm/, or /tɑːˈhoʊnə ˈɑːtəm/) are indigenous Native Americans who reside primarily in the Sonoran Desert of southern Arizona and northwestern Mexico. Tohono O’odham means "Desert People." The federally recognized tribe is known as the Tohono O'odham Nation. The Tohono O’odham have rejected the former name Papago, used by Europeans after being adopted by Spanish conquistadores from hearing other Piman bands call them this. The Pima were competitors and referred to the people as Ba:bawĭkoʼa, meaning "eating tepary beans." That word was pronounced papago by the Spanish and adopted by later English speakers. The Tohono O'odham Nation, or Tohono O’odham Indian Reservation, is a major reservation located in southern Arizona, encompassing portions of Pima County, Pinal County, and Maricopa County.
