The Albanian Greek Catholic Church, or the Albanian Byzantine Catholic Church, is an autonomous Byzantine Rite particular church in full communion with the Catholic Church and the Pope of Rome, whose members live in Albania and which comprises the Apostolic Administration of Southern Albania. The Albanian Greek Catholic Church, with its Byzantine Rite, is closely linked to the Italo-Albanian Catholic Church sharing a significant commonality of history, identity and traditions.

The Italo-Albanian Catholic Church or Italo-Albanian Byzantine-Catholic Church is one of the 23 Eastern Catholic Churches which, together with the Latin Church, compose the Catholic Church. It is an autonomous (sui juris) particular church in full communion with the Pope of Rome, directly subject to the Roman Congregation for the Oriental Churches, but which follows the Byzantine Rite, the ritual and spiritual traditions that are common in most of the Eastern Orthodox Church. It uses two liturgical languages: Koine Greek, the traditional language of the Eastern Churches, and Albanian, the native language of most of its adherents.
