The Beaverfoot Formation is a stratigraphic unit of Late Ordovician (Ashgill age) to Early Silurian (Llandovery) age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains of British Columbia and Alberta, and the Purcell Mountains of British Columbia. It consists of carbonate rocks, and was named for the Beaverfoot Range at Pedley Pass southeast of Golden, British Columbia by L.D. Burling in 1922.
The formation is fossiliferous and is known for its brachiopod faunas. It also contains rugose corals and conodonts.
