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, comprise the Catholic Church. It is an autonomous (sui juris) particular church in full communion with the pope of Rome, directly subject to the Roman Dicastery for the Oriental Churches. It 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 Italo-Albanian Catholic Church extends its jurisdiction over the Italo-Albanian people, who are the descendants of the exiled Albanians that fled to Italy in the 15th century under the pressure of the Turkish persecutions in Albania, Epirus and the Morea (Peloponnese). For over five centuries, they have managed, as a diaspora, to retain their language, culture, customs and beliefs. Nowadays, they reside primarily in Southern Italy (Abruzzo, Apulia, Basilicata, Calabria) and in Sicily, as well as in Central Italy, where they are present only in the Monastery of Grottaferrata in the Lazio region. The Church also operates among the Italo-Albanian diaspora in North and South America. It has about 80,000 faithful. It does not have a metropolitan, but is instead led by two eparchs and a territorial abbot.

The Territorial Abbacy of Santa Maria of Grottaferrata is an ecclesiastical jurisdiction which administers the Byzantine Rite Abbey of Saint Mary in Grottaferrata located in Grottaferrata, Rome, Lazio, Italy.

The Abbacy and its territory are stauropegic, that is, directly subordinate to a primate or synod, rather than to a local bishop. It is the only remnant Eastern Christian monasticism of Byzantine tradition in Italy, further brought to the monastery by the Italo-Albanians, the only ones to historically preserve the Byzantine rite on the peninsula. It is also the only monastery of the Italian Basilian Order of Grottaferrata, (abbreviated O.S.B.I.), a religious order of the Italo-Albanian Greek Catholic Church. The abbot ordinary is also the superior general of the Italian Basilian Order of Grottaferrata. Though normally led by an abbot, the Abbacy has been under the authority of Bishop (now Cardinal) Marcello Semeraro since Pope Francis named him Apostolic Administrator of the Abbacy on 4 November 2013.

Rocca di Papa (Roman Castles Romanesco: 'A Rocca) is a small town and comune (municipality) in the Metropolitan City of Rome, Lazio, Italy. It is one of the Castelli Romani about 25 kilometres (16 mi) southeast of Rome on the Alban Hills. It is close to the other communes of Velletri, Rocca Priora, Monte Compatri, Grottaferrata, Albano and Marino. It is the center of the Regional Park known as the "Parco Regionale dei Castelli Romani".

Marino (Latin: Marinum or Castrimoenium, Marino dialect: Marini) is an Italian comune with 46,676 inhabitants located in the Metropolitan City of Rome Capital in Lazio.

Situated south of the capital, on the Alban Hills in the area of the Roman Castles, nestled between Rocca di Papa, Castel Gandolfo, and Grottaferrata, the town was a significant military outpost on the Ager Romanus throughout the Middle Ages, a popular vacation destination, and an important commercial hub due to its strategic position on the highway between Rome and Naples, which was frequented until the reopening of the faster Via Appia Nuova around 1780.
