The Mount Hawk Formation is a stratigraphic unit of Late Devonian (late Frasnian) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains and foothills of Alberta. It consists primarily of limestone and mudstone, and was named for Hawk Mountain in Jasper National Park by R. de Wit and D.J. McLaren in 1950.[1][2]

The Mount Hawk Formation is fossiliferous and preserves remains of marine animals such as Syringopora and other corals, and brachiopods.[1]
