Rastodon is a genus of dicynodont, an extinct group of herbivorous therapsids (the group to which modern mammals belong) from the Guadalupian (middle Permian) of Brazil. The type and only species is R. procurvidens, named in 2016 for its forward-curving tusks, unique among dicynodonts. Rastodon is one of the only dicynodonts known from the Permian period of South America. Rastodon was initially described as the earliest member of Bidentalia, a derived group of dicynodonts, and though this relationship was regarded with some scepticism, it was not until 2025 that the specimen was re-examined and reinterpreted as a member of the dicynodont family Kingoriidae.
