Pliogonodon is an extinct genus of crocodylomorph. The type species, P. priscus, was named by Joseph Leidy in 1856. The holotype, known as USNM 7448, is a worn and broken tooth found from Phoebus Landing on the Cape Fear River in North Carolina. Although the age of the strata in which the tooth was found was not recorded, it is thought to have come from Miocene-age beds. The holotype and another tooth found at the same location are all that is known from the genus.
