Diplocaulus (meaning "double caul") is an extinct genus of lepospondyl amphibians from the Permian period of North America. It is one of the largest lepospondyls, with a distinctive boomerang-shaped skull. Remains attributed to Diplocaulus have been found from the Late Permian of Morocco and represent the youngest known occurrence of a lepospondyl.
