Polybus (Ancient Greek: Πόλυβος) son of Antenor is a Trojan prince who stands with Hector, Polydamas, Aeneas, and his brothers Agenor and Acamas when battle rages about the ships. Quintus Smyrnaeus also places him among Antenor's sons. He is distinct from Polybus of Corinth (Oedipus' foster-father) and from Penelope's Ithacan and Zacynthian suitors of the same name.

I.Antenorid at Troy
Iliad 11.59–71 gathers the Trojans about Hector, Polydamas, Aeneas, and Antenor's three sons — Polybus, goodly Agenor, and young Acamas. Homer fixes this Polybus among the Dardanian princes rather than among Ithaca's wooers.
