The Tohono O’odham are a group of Native Americans who reside primarily in the Sonoran Desert of eastern Arizona and northwestern Mexico.

"Tohono O’odham" means "Desert People".

The governmental entity for the tribe is the Tohono O'odham Nation.Although the Tohono O’odham were previously known as the Papago, (meaning "tepary-bean eater"), they have largely rejected this name.

It was applied to them by conquistadores who had heard them called this by other Piman bands that were very competitive with the Tohono O’odham.

The term Papago derives from Ba:bawĭkoʼa, meaning "eating tepary beans."

That word was pronounced papago by the Spanish.The Tohono O'odham Nation, or Tohono O’odham Indian Reservation, is located in southern Arizona, encompassing portions of Pima County, Pinal County, and Maricopa County.
