In Greek mythology, Spercheus or Spercheios (Greek: Σπερχειός) was the name of a river in Thessaly (present Spercheios River), and of the god of that river. According to Antoninus Liberalis (22), the nymphs of Mount Othrys were daughters of Spercheus by Deino, whether the same Deino elsewhere named as one of the Graeae or another is not said. Liberalis also says that King Dryops of Oeta was son of Spercheus by Polydora daughter of Danaus, the same Dryops who was father of Dryope. In Homer's Iliad, Spercheus was the father of Menesthius, one of Achilles's commanders, by Achilles' half-sister Polydora.
