The Gila River Indian Community (GRIC) (O'odham language: Keli Akimel Oʼotham, meaning "Gila River People", Maricopa language: Pee-Posh) is an Indian reservation in the U.S. state of Arizona, lying adjacent to the south side of the cities of Chandler and Phoenix, within the Phoenix Metropolitan Area in Pinal and Maricopa counties.

[1] It is made up of seven districts[2] along the Gila River and its largest communities are Sacaton, Komatke, Santan, and Blackwater.

The Community operates its own telecom company, electric utility, industrial park and healthcare clinic, and publishes a monthly newspaper.

I-10 was built through the southeast to north-central portion of Gila River lands, bringing significant highway traffic through the area.

The Constitution and Bylaws of the Gila River Indian Community of Arizona was ratified by the tribe January 22, 1960, and approved by the US Secretary of the Interior on March 17, 1960.
