The Gila River Indian Community of the Gila River Indian Reservation is federally recognized tribe of Native Americans. The tribe controls the Gila River Indian Reservation, a reservation in the U.S. state of Arizona, lying adjacent to the south side of the cities of Chandler and Phoenix, in the Phoenix Metropolitan Area in Pinal and Maricopa counties. The reservation was established in 1859, and the Gila River Indian Community (GRIC) was formally established by Congress in 1939. This tribe has citizens who belong to two ethnic groups, the Akimel O’odham and Maricopa. The O'odham language name for the community is Keli Akimel Oʼotham, meaning "Gila River People".
