Anoa, also known as dwarf buffalo and sapiutan, are two species of the genus Bubalus, placed within the subgenus Anoa and endemic to the island of Sulawesi in Indonesia: the mountain anoa and the lowland anoa. Both live in undisturbed rainforests and are similar in appearance to miniature water buffaloes, weighing 150–300 kg (330–660 lb).

Bubalus is a genus of Asiatic bovines that was proposed by Charles Hamilton Smith in 1827. Bubalus and Syncerus form the subtribe Bubalina, the true buffaloes.
