Dihoplus is an extinct genus of rhinoceros that lived in Eurasia from the Late Miocene to Pliocene.

The genus is now generally considered distinct,[3] though there is still debate as to which species should be included; for example, Deng (2011) listed Merck's rhinoceros (Stephanorhinus kirchbergensis) under Dihoplus.

[4] Species recently placed in the genus include:[5] "D." megarhinus (de Christol, 1834) from the Late Miocene-Pliocene of Europe, Anatolia, China and Transbaikalia,[1][5] since 2021 has been placed instead in the genus Pliorhinus along with "Dicerorhinus" miguelcrusafonti from the Pliocene of Europe.

[8] The monophyly of the genus has been questioned, with some studies suggesting that D. pikermiensis is more closely related to Stephanorhinus and Coelodonta (which contains the woolly rhinoceros) than to the type species D.
