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.

The Arbëreshë, also known as Albanians of Italy or Italo-Albanians, are an Albanian ethnolinguistic group minority historically settled in Southern and Insular Italy.
