Dicerorhinus (Greek: "two" (dio), "horn" (keratos), "nose" (rhinos)) is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros (D. sumatrensis), and several extinct species. The genus likely originated from the Late Miocene of central Myanmar. Many species previously placed in this genus probably belong elsewhere. originally described as Rhinoceros fusuiensis Early Pleistocene, South China.

  • †Dicerorhinus gwebinensis <small>Zin-Maung-Maung-Thein et al., 2008</small> Known from a skull of Pliocene-Early Pleistocene age found in Myanmar. Some authors have considered the skull not distinguishable from that of D. sumatrensis.

Historically, Dicerorhinus was a wastebasket taxon. Revisions by several authors over the years have removed many species:
