Chief Plenty Coups State Park and Home, Native American cultural site in Pryor, Montana.

Chief Plenty Coups State Park is a reservation-based site in Montana featuring historic structures and natural settings. The property includes a traditional log residence, a sacred spring, and visitor facilities positioned within a mountain landscape.

The land was granted to a tribal leader through an allotment program around 1884, allowing him to establish a private homestead. The site marks a period when tribal nations had to reconsider their paths forward.

The park holds the only museum of Apsáalooke culture in the United States, with a memorial to Plenty Coups. On Labor Day weekend the Day of Honor brings Crow dancers and free food, open to all. The 1903 apple trees are listed as a Heritage Orchard.

The park lies about 0.5 miles (0.8 km) west of Pryor on the Crow Indian Reservation, with a separate 6.2-acre (2.5 ha) parcel added around 1970 for access and park structures. The visitor center and museum, built in 1972, and the Chief's House are open to the public, and the grounds are open year-round. The park runs school and group education programs, and its main event is the Day of Honor over Labor Day weekend.

The family put their intention in writing during their lifetime that the property should become public after they were gone. This was uncommon at the time and shows a deliberate choice to share their legacy.
