Rough Rider State Park is a public recreation area located along the eastern banks of the Little Missouri River about two miles (3.2 km) south of Medora in Billings County, North Dakota.

[4] The Rough Riders was a nickname given to the 1st United States Volunteer Cavalry when it was led by Theodore Roosevelt.

His presidential library is under construction nearby as Roosevelt hunted and ranched in the area in the 1880s.

[5] The park is the starting point for the Maah Daah Hey Trail which winds northwards to Theodore Roosevelt National Park and is used by horseback riders, mountain bikers, and hikers.

The park offers camping, equestrian facilities, and canoe access to the Little Missouri River.
