Fort Shaw (originally named Camp Reynolds) was a United States Army fort located on the Sun River 24 miles west of Great Falls, Montana, in the United States. It was founded on June 30, 1867, and abandoned by the Army in July 1891. It later served as a school for Native American children from 1892 to 1910. Portions of the fort survive today as a small museum. The fort lent its name to the community of Fort Shaw, Montana, which grew up around it. Fort Shaw is part of the Fort Shaw Historic District and Cemetery, which was added to the National Register of Historic Places on January 11, 1985.
