Notoceratops (meaning "southern horned face") is a dubious genus of extinct ornithischian dinosaur. The genus was described based on an incomplete, toothless left dentary (now lost) from the Late Cretaceous of Patagonia (in Argentina), probably dating to the Campanian or Maastrichtian. Initially classified as a putative ceratopsian found in the Lago Colhué Huapi Formation, the lost fragmentary holotype precludes confident referral of this taxon within ornithischians, with some researchers suggesting that it belongs to a hadrosaur instead.
