The Visayan warty pig is a critically endangered species in the pig genus (Sus). It is endemic to six of the Visayan Islands in the central Philippines. It is known by many names in the region with most translating into 'wild pig': baboy ilahas, baboy talonon, baboy sulop, and baboy ramo.

Sus is the genus of wild and domestic pigs, within the even-toed ungulate family Suidae. Sus include domestic pigs and their ancestor, the common Eurasian wild boar, along with other species. Sus species, like all suids, are native to the Eurasian and African continents, ranging from Europe to the Pacific islands. Suids other than the pig are the babirusa of Indonesia, the pygmy hog of South Asia, the warthogs of Africa, and other pig genera from Africa. The suids are a sister clade to peccaries.
