Phacochoerus is a genus of wild pigs in the family
Suidae, known as
warthogs. It is the sole genus of
subfamily Phacochoerinae. They are found in open and semiopen 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 (or simply warthog) is
Phacochoerus africanus.
