Scapanorhynchus (from , 'shovel' and 'snout') is an extinct genus of shark belonging to the family Mitsukurinidae, that lived during the Cretaceous period, from the Aptian to the end of the Maastrichtian. It is a close relative of the living goblin shark (Mitsukurina owstoni), the only living member of the family. Later claimed records of Scapanorhynchus, such as those from the Miocene assigned to the species S. subulatus, are highly dubious and may be misidentified sand sharks.
