Grisette Mountain is a 2,620-metre summit in Jasper National Park, Alberta, in the Colin Range of the Canadian Rockies. About 14 kilometres northeast of Jasper, it is a prominent landmark in the Athabasca Valley, visible from Highway 16 and the Canadian rail line. Dominion Land Surveyor Morrison P. Bridgland named it in 1916 for its gray limestone, drawing on the French word gris for gray; the Geographical Names Board of Canada officially adopted the name in 1947. The mountain has a subarctic climate with cold, snowy winters and mild summers, and its runoff feeds tributaries of the Maligne and Rocky rivers within the Athabasca River system.
