Isidore II Xanthopoulos (Greek: Ισίδωρος Β΄ Ξανθόπουλος) was Ecumenical Patriarch of Constantinople from 1456 to 1462.
Little is known about the life and the patriarchate of Isidore. His surname derives from the Xanthopoulon monastery in Istanbul which he entered, becoming a hieromonk and later rising to be its abbot.[2] Isidore worked alongside Gennadius Scholarius during the Council of Florence[3] and was one of the signatories of a 1445 document against the East-West Union of Churches.[4] In this period Isidore was deemed as the spiritual father of the Greek community in Istanbul.[3]
After the resignation of Gennadius Scholarius as Patriach in mid-January 1456, Isidore was elected to succeed him. He obtained the confirmation from Sultan Mehmed II and he was consecrated bishop in the Pammakaristos Church.[5]
His reign lasted up to his death on 31 March 1462,[2] and he was succeeded by Joasaph I.[1]
