The Cache Creek Terrane is a geologic terrane in British Columbia and southern Yukon, Canada. It consists of Carboniferous to Lower Jurassic volcanic rocks, carbonate rocks, coarse clastic rocks and small amounts of ultramafic rock, chert and argillite. Three geological formations comprise the Cache Creek Terrane: the Sitlika Assemblage, the Tezzeron succession and the Cache Creek Complex.
