Epiaceratherium is an extinct genus of rhinocerotid from the Eocene and Oligocene of Europe, Asia, and North America.

This species is exclusively known from remains found at Monteviale in northern Italy, dating to the earliest Oligocene (~34 million years ago).

[1] In 2013 the species Epiaceratherium naduongense was described from Na Duong Basin in northern Vietnam, dating to the mid-late Eocene (~39–35 million years ago).

[1] Undescribed remains have been reported from Haughton crater in the high Canadian Arctic likely dating to the early Miocene.
