Phacochoerus is a genus in the family Suidae, commonly known as warthogs. It is the sole genus of subfamily Phacochoerinae. They are pigs who live in open and semi-open habitats, even in quite arid regions, in sub-Saharan Africa. The two species were formerly considered conspecific under the scientific name Phacochoerus aethiopicus, but today this is limited to the desert warthog, while the best-known and most widespread species, the common warthog is Phacochoerus africanus.
