Margos of Elaea (471 BC-) was Basileus of the Thessalian League from 429 BC, succeeding Skopas. In 429 BC, during the Peloponnesian War, he raised an army at the former Epirote city of Elaea to suppress Epirote unrest and to defend the region from the Peloponnesian League. On Skopas' death at the Battle of Kompoti that same year, he became the new ruler of the Thessalian League, although his territory was confined to the area around Elaea.
