The Salt River Pima–Maricopa Indian Community (SRPMIC) comprises two distinct Native American tribes—the Pima and the Maricopa —many of whom were originally part of the Halchidhoma (Xalchidom) tribe. The community was permanently created by an Executive Order of US President Rutherford B. Hayes on June 14th, 1879. The community area includes 53,600 acres (217 km2), of which 19,000 remain a natural preserve. As of 2022, the total population is 7,386. The community is a federally recognized tribe located in Arizona.

The Akimel O'odham, also called the Pima, are a group of Native Americans living in an area consisting of what is now central and southern Arizona, as well as northwestern Mexico in the states of Sonora and Chihuahua. The majority population of the two current bands of the Akimel O'odham in the United States are based in two reservations: the Keli Akimel Oʼodham on the Gila River Indian Community (GRIC) and the On'k Akimel O'odham on the Salt River Pima-Maricopa Indian Community (SRPMIC).
