Orycterocetus quadratidens is an extinct sperm whale from the Miocene of the northern Atlantic Ocean and the type species of the genus Orycterocetus, first named by Joseph Leidy in 1853. Leidy based it on two teeth, two partial mandibular rami and a rib from Neogene deposits of Virginia. The genus is a member of the superfamily Physeteroidea and is closely related to the crown-group sperm whales, and it is thought to have been similar in size to Acrophyseter. Two more species were later placed in the genus: O. cornutidens, named by Leidy in 1856, and O. crocodilinus, named by Cope in 1868 from the middle Miocene Calvert Formation.
