Buffalo Bill State Park is located in Cody, Wyoming. The park is built around the reservoir created by the Buffalo Bill Dam on the Shoshone River. The park is owned and operated by the state of Wyoming via the State Park, Historic Sites, & Trails office.

Named after William Cody, one of the most famous and colorful figures of the Old West, the park is built on land owned and sold to the government by Cody himself. The park was established in 1957 around the Shoshone Dam reservoir. The dam itself was completed in 1910 as one of the highest dams in the world. The park was closed and rebuilt in 1993 after the dam height was increased. The old park facilities were flooded by the resulting increase in the size of the reservoir. The park visitors center was opened at the same time as the completion of the dam renovation.
