Gila River Indian Reservation was a reservation established in 1859 by the United States government in New Mexico Territory, to set aside the lands of the Akimel O’odham (Pima) and the Pee-Posh (Maricopa) people along the Gila River, in what is now Pinal County, Arizona. The self-government of the reservation as the Gila River Indian Community was established by Congress in 1939.
