Unlike most European countries, the Catholic Church in Romania comprises in a single national episcopal conference both Latin and two Eastern Catholic churches (one of which being nation-specific):

• A Latin hierarchy
  • one ecclesiastical province with four suffragan sees
  • an exempt non-metropolitan archdiocese
• Two Eastern Catholic rite-specific particular churches sui iuris:
  • The Romanian Greek Catholic Church (Byzantine Rite (Greek Catholic) in Rumanian language, comprising the Ecclesiastical province of Făgăraş and Alba Iulia, whose Metropolitan Archbishop is the Major Archbishop (almost Patriarch) of the whole rite-specific particular church sui iuris, and all its four Romanian Suffragan Eparchies (dioceses).
  • An Armenian Catholic Ordinariate for Eastern Catholic faithful.

There is also an Apostolic nunciature as papal diplomatic representation (embassy-level) in the national capital Bucharest, into which is also vested the Apostolic nunciature to neighbouring Moldova (Ex-Soviet, ethnic Romanians).
