Hamilton's Stores were concessioners in Yellowstone National Park from 1915 to 2002. The stores were founded by Winnipeg native Charles Hamilton, who arrived in Yellowstone in 1905, aged 21, to work for the Yellowstone Park Association. The stores provided food, souvenirs and sundries to tourists at the major attractions along Yellowstone's Grand Loop Road. Several of the buildings constructed for Hamilton's are significant examples of the National Park Service Rustic style of architecture and have assumed prominence as attractions in their own right. Most or all are included as contributing structures in National Register of Historic Places historic districts.
