Saurocephalus is an extinct genus of fishes within the family Saurodontidae Cope, 1871. Members of this family (saurodontids) were teleostean fishes restricted to the upper Cretaceous. They are placed within the Ichthyodectiformes, an extinct order of fish known from the middle Jurassic to the late Cretaceous with species found in almost every continent of the world. From among the almost 20 genera included in the order, saurodontids are more closely related to Gillicus, Xiphactinus, and Ichthyodectes.
