In Greek mythology, Iolaus (Greek: Ἰόλαος Iólaos) was a Theban divine hero, son of Iphikles and Automedusa.
He was famed for being Herakles's nephew and for helping with Herakles second labor. Ioalos also gained fame for being one of the Argonauts. Through his daughter Leipephilene, he was considered to have fathered the mythic and historic line of the kings of Corinth, ending with Telestes.
