"Promerycochoerus" ("Before "Mercycochoerus" or "Before Ruminating Hog") is an extinct genus of hippopotamus-like oreodont artiodactyl that lived in Central North America during the Early Miocene.

The 1 m (3 ft 4 in) long creature is thought to have been amphibious, as all species possessed an elongated, barrel-shaped body and short limbs that are typical adaptations found in semi-aquatic mammals. "P. superbus" had a long tapir-like face, while "P. carrikeri" had a short, somewhat pig-like face.
