Vetusodon is an extinct genus of cynodonts belonging to the clade Epicynodontia. It contains one species, Vetusodon elikhulu, which is known from four specimens found in the Late Permian Daptocephalus Assemblage Zone of South Africa. With a skull length of about , Vetusodon is the largest known cynodont from the Permian. Through convergent evolution, it possessed several unusual features reminiscent of the contemporary therocephalian Moschorhinus, including broad, robust jaws, large incisors and canines, and small, single-cusped postcanine teeth.

== Discovery and naming == Vetusodon is known from four specimens, all of which have been collected in South Africa from rocks belonging to the Daptocephalus Assemblage Zone. The holotype, BP/1/7971, consists of a well-preserved skull missing the lower jaw. It was discovered in 2010 in a mudstone bed in the province of KwaZulu-Natal by a team led by the palaeontologist Bruce S. Rubidge. The referred specimen CGP GHG141 was found in 1985 by Gideon Groenewald in the Thaba Nchu Mountain of the Free State province, and like the holotype, it consists of a partial skull missing the lower jaw. The specimen SAM-PK-K10596 is the least complete of the specimens, consisting only of a snout. It was found in 1958 or 1959 by the South African palaeontologist Alfred W. Crompton. The specimen SAM-PK-K10702 is the most complete of the four specimens, and comprises a complete skull with an intact lower jaw. It was discovered in 2009 or 2010 by Derik Wolvaardt at the Ripplemead Farm, close to the town of Nieu-Bethesda, Eastern Cape province.
