Lists of leaders of the Ukrainian Greek Catholic Church

This is a list of leaders of the Ukrainian Greek Catholic Church (formerly known as the Ruthenian Uniate Church or the Uniate Church) which is a sui juris (particular church) of the Catholic Church that is in full communion with the Holy See. As an Eastern Catholic church, it uses the Byzantine rite in the Church slavonic and Ukrainian languages in its liturgies. Leaders have held several titles over the centuries. The modern primate of the church holds the position of a major archeparch (also styled as "major archbishop").

Due to historical circumstances (i.e. Russian occupation), the first hierarchs of the Ukrainian Greek Catholic Church held titles that did not mention the original metropolitan city of Kyiv. It is common for people to refer to the major archbishop as a "Primate". However, only Mykhailo Levitsky officially held that title which was granted by the Austrian Emperor as the Primate of Halychyna and Lodomeria, but not approved by the Pope.
