Perchoerus is an extinct genus of peccary from Eocene and Oligocene of North America. Three species are known.[1][2]

Perchoerus is notable for being the oldest peccary from North America, colonizing the continent via Asia approximately 37 mya. The oldest known species of Perchoerus is P. minor, which was only the size of a house cat. It is known from skull and tooth material. The later P. nanus of the Orellan grew larger and is known from a skull and lower jaw. The latest and largest species was P. probus of the Oligocene (32-30 mya). It was much larger (about as big as living peccaries) and known from more remains than the other species.[1][3]
