Mazyar (Middle Persian: Māh-Izād; Persian: مازیار‎‎ Mazyār), was an Iranian prince from the Qarinvand dynasty and feudal ruler of the mountainous region of Tabaristan. For his resistance to the Abbasid Caliphate, Maziyar is considered one of the national heroes of Iran by twentieth-century Iranian nationalist historiography. His name means "protected by the yazata of the moon".
