Metridiochoerus is an extinct genus of swine known from the Pliocene and Pleistocene of Africa.

The oldest specimen dates to around 3.4 million years ago from the Usno Formation in Ethiopia.

[1] It probably evolved from a recent immigrant from Eurasia, which has been suggested to be the European "Postpotamochoerus" provincialis.

[3] Metridiochoerus was a large animal, 1.5 metres (4.9 ft) in length, resembling a giant warthog.

It had two large pairs of tusks which were pointed sideways and curved upwards.
