Greek Catholic Eparchy of Mukachevo

The Greek Catholic Eparchy of Mukachevo is an eparchy (diocese) of the Ruthenian Greek Catholic Church that was erected by the Pope Clement XIV in 1771. The geographic remit of the eparchy includes the south-western parts of Ukraine that are roughly within Zakarpatska Oblast. As an Eastern Catholic Church, it is in full communion with the Catholic Church. The eparchy is exempt, which means that it does have a metropolitan bishop but is directly subject to the Holy See. It is supervised by the Roman Dicastery for the Eastern Churches, a Roman Curia dicastery acting on behalf of the Pope. Its parishes observe the Byzantine Rite which is also celebrated by the majority of Orthodox Christians, and as provided for in the original terms of the Union of Uzhhorod. The episcopal seat is the Cathedral of the Exaltation of the Holy Cross in the city of Uzhhorod.

The eparchy is a mother eparchy of four modern metropolises: the Slovak Greek Catholic Church, the Romanian Greek Catholic Church, the Hungarian Greek Catholic Church, and the Ruthenian Greek Catholic Church.
