The Slave Point Formation is a stratigraphic unit of Middle Devonian age in the Western Canadian Sedimentary Basin.
It takes the name from Slave Point, a promontory on the north-west shore of the Great Slave Lake, and was first described in outcrop on the southern shore of the lake and along the Buffalo River by A.E. Cameron in 1918. It was subsequently defined in the subsurface by J. Law in 1955, based on lithology encountered in the California Standard Steen River 2-22-117-5W6M well in Alberta.
