Eupatorus gracilicornis, the five-horned rhinoceros beetle (Thai: ด้วงกว่างซางเหนือ (DâwŋGwā̀ŋŞāŋĦeNǖx)) is a beetle that has four large horns on the prothorax and one extra-long cephalic horn.

The five-horned rhinoceros beetle has been found in China, India, Myanmar, Thailand, Laos and Vietnam.

The body is covered by a thick exoskeleton and a pair of thick wing covers lay atop another set of membranous wings underneath, allowing the beetle to fly, although not very efficiently, owing to its large size.

The flying season is usually in September, when most of the males usually appear to wait for copulation.

Its adult diet consists of nectar, plant sap and fruit.
