Leptotragulus is an extinct genus of protoceratid, endemic to North America.

It lived during the Middle Eocene epoch (Uintan to Chadronian stage) 40.2—33.9 Ma, existing for approximately 6 million years.

In addition to having horns in the more usual place,[clarification needed] many protoceratids had additional, rostral horns above the orbital cavity.

This genus, as well as many other Leptotragulines, was completely hornlees.
