The Cheyenne River Reservation is located in north central South Dakota, with the Missouri River forming its eastern boundary and the Cheyenne River its southern boundary. The reservation makes up the entirety of two South Dakota counties: Dewey and Ziebach. Eagle Butte, the largest city, is home to the Tribal headquarters. Residents live in one of 16 tribal communities or in scattered rural homes across the reservation. It is the fourth largest reservation in the United States, known for its rolling prairies and abundance of water.
