The Skoki Formation is a stratigraphic unit of Early to Middle Ordovician age that is present on the western edge of the Western Canada Sedimentary Basin in the Canadian Rockies of Alberta and British Columbia.

[3] It was named for Skoki Mountain near Lake Louise in Banff National Park by Charles Doolittle Walcott in 1928.

[2] The Skoki Formation is fossiliferous and includes remains of brachiopods and other marine invertebrates, as well as conodonts and oncolites.

[1] The Skoki Formation formed as a shallow marine shelf along the western shoreline of the North American Craton during Early to Middle Ordovician time.

[5][1] The Skoki Formation contains several genera of brachiopods, as well as gastropods, conodonts, cephalopods, trilobites, echinoderms, stromatolites, corals, and oncolites.
