Eupatorus gracilicornis, the five-horned rhinoceros beetle (Thai : ด้วงกว่างซางเหนือ) is a beetle that has four large horns on the prothorax and one extra-long cephalic horn. Rhinoceros beetles, the Dynastinae, are a subfamily of the scarab beetle family (Scarabaeidae).

The five-horned rhinoceros beetle has been found in China, India, Myanmar, Thailand, Laos and Vietnam.^[2] Its coloring is shiny jet-black, while the elytra or fore wings are colored yellow or gold. 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.
