Tritemnodon ("three cutting teeth") was an extinct genus of placental mammals from extinct order Hyaenodonta, that lived in North America during the early Eocene. Fossils of Tritemnodon agilis have been found in Utah and Wyoming (Willwood Formation of Big Horn County and the Lower Bridger Formation of Uinta County). It was the size of a wolf.
