Metatomarctus is an extinct genus of the Borophaginae subfamily of canids native to North America. It lived during the Early to Middle Miocene, 23–16 Mya, existing for approximately 7 million years It was an intermediate-size canid, and more predaceous than earlier borophagines.

It hunted in packs, like modern canines, and may have preyed upon creatures such as Equus, rodents, and other smaller prey.
