Hamber Provincial Park is a provincial park in British Columbia, Canada, located at the provincial boundary with Alberta, surrounded on three sides by Jasper National Park. When the park was created in 1941, it constituted one of the largest protected wilderness areas in Canada. In the early 1960s, the provincial government reduced its size by 98% due to pressure exerted by the forestry industry, planned hydroelectric developments along the upper Columbia River and the re-routing of the Trans-Canada Highway away from the park.
