Gregory the Bulgarian

Gregory the Bulgarian, or Gregory II (fl. 1458 – d. 1474) was Metropolitan of Kiev, Galicia and all Rus'. His title to the metropolitan see was acknowledged both by the Holy See and by the Ecumenical Patriarchate of Constantinople due to their joint acceptance of the Council of Florence which united the Latin and the Eastern Orthodox Churches for a short period of time.

He was consecrated by the Patriarch of Constantinople — Gregory III — in 1458. His canonical territory was the western part of the traditional Kievan Rus' lands — the states of the Grand Duchy of Lithuania and the Kingdom of Poland. The episcopal seat was in the city of Navahrudak which is today located in Belarus.
