Colepiocephale is a genus of pachycephalosaurid dinosaur. The type species, C. lambei, was originally described by Sternberg (in 1945 as Stegoceras lambei), and later renamed by Sullivan in 2003. C. lambei is a domed pachycephalosaur characterized principally by the lack of a lateral and posteriosquamosal shelf, a steeply down-turned parietal, and the presence of two incipient nodes tucked under the posterior margin of the parietosquamosal border.
