Peneleos (Ancient Greek: Πηνελέως; also Peneleus) was a Boeotian leader in the Trojan War, son of Hippalcimus and Asterope. An Argonaut and former suitor of Helen, he commanded Boeotian ships in Homer's Catalogue and killed Trojans including Ilioneus and Lycon before falling — in later epic — to Eurypylus son of Telephus. His grandson Damasichthon later ruled Thebes.

I.Before Troy
Apollodorus counts Peneleos among the Argonauts and among Helen's suitors, which bound him to the Trojan campaign. Pausanias says he was chosen to lead the Boeotians because Tisamenus, son of Thersander, was still too young. When Poemander accidentally killed his own son Leucippus while dodging war service, Peneleos was among those who took him to Elephenor on Chalcis for purification.
II.At Troy and after
In the Iliad Peneleos fights among the Boeotian captains (Homer gives the contingent fifty ships under five leaders). He slays Ilioneus and Lycon, is wounded by Polydamas, and — in Dictys — is killed by Eurypylus son of Telephus. He left a son Opheltes; Opheltes' son Damasichthon succeeded Autesion as ruler of Thebes. A later descendant, Philotas of Thebes, was said to found Priene in Ionia.
