Ceratosaurus (sayr-AT-oh-sawr-us) meaning "horned lizard", in reference to the horn on its nose (Greek kerat = horned + sauros = lizard) is a predatory dinosaur from the Late Jurassic Morrison Formation of North America. It is characterized by large jaws with enormous, bladelike teeth, a large, bladelike horn on the snout, and a pair hornlets over the eyes. The forelimbs were powerfully built but very short. The type species is Ceratosaurus nasicornis, although several other species have been named, including C. dentisulcatus and C. magnicornis, and there is some controversy over the exact number of species. A conservative view favors three (C. nasicornis, magnicornis, and dentisulcatus), but a liberal view favors several additional species, including C. ingens, C. stechowi, and a species that has been referred to as C. meriani, from Portugal.

Ceratosaurus is known from the Cleveland-Lloyd quarry in central Utah and Dry Mesa in Colorado. It lived alongside dinosaurs such as Allosaurus, Torvosaurus, Apatosaurus, Diplodocus, and Stegosaurus. Some suggest it was a rival to Allosaurus.

Ceratosaurus was around 4.5–6 m in size, weighing 500 kg up to 1 tonne. The African C. ingens may have been much larger, with size estimates ranging up to 5 tonnes, which if correct would make it one of the largest of the Theropoda.

Relatives of Ceratosaurus include Elaphrosaurus and the abelisaur Carnotaurus.
