Romanian Greek Catholic Church

The Romanian Greek Catholic Church, or Romanian Church United with Rome, is a sui iuris Eastern Catholic Church in full union with the Catholic Church. It has the rank of a major archiepiscopal church and uses the Byzantine liturgical rite in the Romanian language. It is one of the major archiepiscopal churches of the Catholic Church which are not distinguished with a patriarchal title.

Cardinal Lucian Mureșan, Archbishop of Făgăraș and Alba Iulia, served as the head of the Romanian Greek Catholic Church from 1994 until his death in September 2025. On December 16, 2005, as the Romanian Church United with Rome, the Greek Catholic church was elevated to the rank of a major archiepiscopal church by Pope Benedict XVI, with Lucian Mureșan becoming its first major archbishop. Mureşan was made a cardinal at the consistory of February 18, 2012.

Besides the Archeparchy of Făgăraș and Alba Iulia, there are five more Greek-Catholic eparchies in Romania (Eparchy of Oradea Mare, Eparchy of Cluj-Gherla, Eparchy of Lugoj, Eparchy of Maramureș, and Eparchy of Saint Basil the Great of Bucharest), as well as one eparchy overseas, the Romanian Catholic Eparchy of St George's in Canton, answering directly to the major archbishop and the Holy See, in the United States of America and Canada.

According to data published in the 2016 Annuario Pontificio, the Romanian Greek Catholic Church had 504,280 members, 8 bishops, 1,225 parishes, some 835 diocesan priests and 235 seminarians of its own rite at the end of 2012. However, according to the 2011 Romanian government census, the number of its followers living in Romania was as low as 150,593, of whom 124,563 are ethnic Romanians. By 2022, however, the church estimated their numbers have grown to 488,000, as many citizens whose ancestors had converted to Orthodoxy or embraced Marxist-Leninist atheism under the communist regime have chosen to rejoin the Greek Catholic Church.

The vast majority of the Romanian diocesan priests in Romania are married.

There are five other Catholic dioceses of the Latin Church in Romania and whose members are more numerous.
