Anthodon (meaning "flower tooth") is an extinct genus of pareiasaur parareptile from the Permian period of South Africa and Tanzania.

In 1845, amateur geologists William Guybon Atherstone and Andrew Geddes Bain discovered several fossils near Dassieklip, Cape Province, in the Bushman's River Valley.

[8] A possible second species, A. minusculus, was named by Sidney Haughton in 1932 based on remains found in the Cistecephalus other zone of the Usili Formation in Tanzania.

Small dermal ossicles covered the body, while the pattern of armor plates on the back reminiscent of a turtle shell.

The cheekbones form very large quadratojugal "horns" that extend downwards to a great degree, but with a smooth unornamented surface.
