Toromeryx is a medium-sized extinct genus of Artiodactyla, of the family Protoceratidae, endemic to southwestern North America from the Eocene epoch (Late Uintan stage) 46.2—42 Ma, existing for approximately 4.2 million years.

Its type is Toromeryx marginensis.

In addition to having horns in the more usual place, protoceratids had additional, rostral horns above the orbital cavity.

Toromeryx was smaller than Miocene members of Tylopoda: Paratoceras, Protoceras, and Pseudoprotoceras.
