The Glacier Park Company, a subsidiary of the Great Northern Railway (GN), constructed and operated hotels, chalets, and other visitor facilities in Glacier National Park, Montana and Waterton Lakes National Park, Alberta from the 1910s through 1960. Operating as a concessionaire of the National Park Service, the company operated from a summer base in East Glacier Park, Montana, near the company's flagship Glacier Park Hotel; winter headquarters were in St. Paul, Minnesota. Originally known as the Glacier Park Hotel Company, the corporate name was shortened to Glacier Park Company in 1943.
