The American Indian Exposition, held annually during the first full week in August at the Caddo County Fairgrounds in Anadarko, Oklahoma, is one of the oldest and largest intertribal gatherings in the United States. Sponsored by fifteen tribes (Apache, Arapaho, Caddo, Cheyenne, Comanche, Delaware, Fort Sill Apache, Iowa, Kiowa, Osage, Otoe-Missouri, Pawnee, Ponca, Sac & Fox, and Wichita), representatives from up to fifty other tribes participate in any given year.
