Ceratosauridae is a family of theropod dinosaurs belonging to the infraorder Ceratosauria. The family's type genus, Ceratosaurus, was first found in Jurassic rocks from North America. Ceratosauridae is made up of the genera Ceratosaurus, found in North America, Tanzania, and Portugal, Genyodectes, from the Late Cretaceous of Argentina, and Fosterovenator which is exclusive to North America. Unnamed probable ceratosaurids are known from limited material in the Middle Jurassic of Madagascar, the Late Jurassic of Switzerland, and the Late Jurassic or possibly Early Cretaceous of Uruguay.

Othniel Charles Marsh named the family Ceratosauridae in 1884 to contain the type species, Ceratosaurus nasicornis. Since then, a number of other species have been referred to this family, mainly from the genus Ceratosaurus. Currently recognized ceratosaurid species include C. dentisulcatus, C. magnicornis, and Genyodectes serus. C. stechowi is an undiagnostic ceratosaur.Fosterovenator churei was described in 2014 from material found at Como Bluff, Wyoming, and has also been assigned to this family. No cladistic definition of Ceratosauridae has been proposed.
