COMMUNITY PROFILE: "The Cocopah Sovereignty is the foundation that preserves traditional cultural values and educational empowerment for a healthier way of life." - Cocopah Tribe Vision Statement, Adopted May 2012.

The Cocopah Indian Tribe, known as the River People, have lived along the lower Colorado River for centuries. The Cocopah Reservation was established in 1917, and in 1964 the Tribe established a Tribal Council. The Cocopah Indian Tribe is one of seven descendant Tribes from the Yuman language-speaking people that lived along the Colorado River. Although the Cocopah people had no written language, history and traditions have been passed down orally and through the diaries and journals of outside travelers along the Colorado River. According to the 2018 Census, approximately 1,203 individuals live on the Cocopah Tribe Reservation in Arizona. 

The Cocopah Tribe is located in the southwest corner of Arizona near the California and Mexico borders. The land area consists of more than 6,500 acres along the lower Colorado River, with a land base of 9.4 square miles. The Cocopah Tribe is actively involved in habitat restoration efforts along the Colorado River. The reservation is comprised of three non-contiguous regions: the North, East, and West Reservations. The East and West Reservations are located 15 minutes from each other on either side of the town of Somerton. The North Reservation is located in Yuma.  

The Cocopah Museum and Cultural Center is located on the West Reservation and includes hand-crafted exhibits, meeting space, and a gift shop.  The museum is surrounded by a 1.5-acre park featuring a traditional dwelling replica made from natural elements.  The Cocopah Tribe also operates the Cocopah Casino, Resort, and Conference Center, the Cocopah Speedway Race Track, the Cocopah RV and Golf Resort, and the Cocopah Rio-Colorado Golf Course.
