There were two characters named Epeius (/ɪˈpaɪ.əs/; Ancient Greek: Ἐπειός Epeiós) or Epeus in Greek mythology.

• Epeius, an Elean prince as son of King Endymion. He ran a race at Olympia, against his brothers Aetolus and Paeon, winning his father's kingdom. Epeius' other siblings were Eurycyda and possibly Naxos.^[1] He was married to Anaxiroe, daughter of Coronus, and had one daughter, Hyrmine. King Oenomaus of Pisa was his contemporary.^[2] From him, the Epei derived their name.^[3]
• Epeius, a Greek soldier during the Trojan War and builder of the Trojan horse.^[4]
