Yolande (also Irene) of Montferrat (c. 1274 – 1317 in Drama), also known as Violante, then Empress Eirene or Irene, was the second wife of Andronikos II Palaiologos and thus Empress of the Byzantine Empire. She was the heiress of the Kingdom of Thessalonika and the last surviving member of the ottonian branch of the Aleramici, heirs to the Margraviate of Montferrat.
