In Greek mythology, Protesilaus (Ancient Greek: Πρωτεσίλαος, Protesilaos), was a hero in the Iliad who was venerated at cult sites in Thessaly and Thrace. Protesilaus was the son of Iphicles, a "lord of many sheep"; as grandson of the eponymous Phylacos, he was the leader of the Phylaceans. Hyginus surmised that he was originally known as Iolaus—not to be confused with Iolaus, the nephew of Heracles—, but was referred to as "Protesilaus" after being the first (πρῶτος, protos) to die at Troy.
