Hill City is the oldest existing city in Pennington County, South Dakota, United States. The population was 948 at the 2010 census. Hill City is located 26 miles (42 km) southwest of Rapid City on U.S. Highway 16 and on U.S. Route 385 that connects Deadwood to Hot Springs. Hill City is known as the "Heart of the Hills", a distinction derived from its proximity to both the geographical center of the Black Hills, and the local tourist destinations.
The city has its roots in the Black Hills mining rush of the late 19th century. Tin mining was dominant in the 1880s and led to an influx of capital and people into the area. As the mining industry waned, tourism and timber became increasingly important industries to the area. With the establishment of Mount Rushmore in the 1940s, Custer State Park and the Sturgis Motorcycle Rally, the Black Hills became known as a tourist destination, from which Hill City benefited. In recent years, the city has diversified to become a center for the arts in the area, featuring several art studios and festivals.
Human history in the area that became Hill City, and the greater Black Hills in particular, started by at least 7000 BC. The Arikara arrived by 1500 AD, followed by the Cheyenne, Crow, Kiowa and Pawnee. In the 19th century, the Lakota Sioux claimed the land, calling it Paha Sapa.
