Eucynodontia ("true dog teeth") is a clade of cynodont therapsids including mammals and most non-mammalian cynodonts. The oldest eucynodonts are known from the Early Triassic and possibly Late Permian. Eucynodontia includes two major subgroups, Cynognathia and Probainognathia.[1]

The clade was named by Thomas Kemp in 1982.[2]

In 2001, James Allen Hopson e.a. defined the clade Euynodontia as the least inclusive group containing Mammalia and Exaeretodon.[3]
