Dicerorhinus is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros, and several extinct species. The genus likely originated in the Mid to Late Pliocene of Northern Indochina and South China. Many species previously placed in this genus probably belong elsewhere.

A rhinoceros, commonly abbreviated to rhino, is a member of any of the five extant species of odd-toed ungulates in the family Rhinocerotidae; it can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea. Two of the extant species are native to Africa, and three to South and Southeast Asia.
