Hyaenodonta ("hyena teeth") is an extinct order of hypercarnivorous eutherian mammals, originally classified along with the oxyaenids as part of Creodonta. Hyaenodonts may have evolved in Africa in the Paleocene.

Hyaenodonts differed from Carnivora in that they replaced their deciduous dentition slower in development than carnivorans.
