Potamochoerus (meaning "river pig") is a genus in the pig family (Suidae). The two species are restricted to sub-Saharan Africa, although the bushpig, possibly due to introduction by man, also occurs in Madagascar and nearby islands. Early in the 20th century, there were considered to be as many as five different species within the genus. These were gradually consolidated, until, in the 1970s, it was generally agreed that all were representatives of just a single species (P. porcus). The bushpig was again recognised as a separate species from about 1993.
