Agriochoerus is an extinct genus of scansorial herbivore of the tylopod family Agriochoeridae, endemic to North America.

Other species attributed to the same genus are A. gaudryi, A. guyotianus, A. crassus, A. major, A. maximus, and A. minimus, all coming from the Eocene–Oligocene of North America.

Agriochoerus is the eponymous genus of the Agriochoeridae, a group of artiodactyl mammals similar to Merycoidodontidae, but distinguishable from the latter for a series of characteristics of the skeleton and of the dentition.

[3] The morphology of the teeth indicates that Agriochoerus shows that this animal was herbivorous, even if the "feline" skeletal anatomy and the presence of claws (as opposed to hooves) are more reminiscent of carnivores.

[4] Based on its high tooth enamel δ13C values, A. antiquus lived in open, dry environments.
