Jonah Metropolitan of Moscow

Saint Jonah or Saint Jonas (Иона in Russian) (died 1461?), was the Metropolitan of Kiev and All Rus' from 1448 to his death in 1461. Like his immediate predecessors, he permanently resided in Moscow, and was the last Moscow-based primate of the Russian Church to keep the traditional title with reference to Kiev. He was also the first Metropolitan in Moscow to be appointed without the approval of the Ecumenical Patriarch of Constantinople as had been the norm.

Since the late 1420s, Jonah had been living in the Simonov Monastery in Moscow and was close to Metropolitan Photius, who make him Bishop of Ryazan and Murom. After Photius's death in 1431, Grand Prince Vasili II nominated Jonas for the post of Metropolitan, but the Uniate Patriarch Joseph II chose Isidore to become the Metropolitan of Kiev and All Rus'.

After Isidore had been condemned and deposed by Vasily II and his bishops in Moscow in 1441, for his attempts to implement the decision on the Union of the Eastern and Western (Roman) Churches agreed upon at the Council of Florence-Ferrara, the metropolitan throne sat vacant for seven years.

Jonah was elected by the bishops of the Moscow Rus' Metropolitan on 15 December 1448, without the consent of the Patriarch of Constantinople. While the failure to obtain the blessing from Constantinople was not intentional, this signified the beginning of the de facto independence () of the Moscow (North-Eastern) part of the Russian Church.
