The Greek Orthodox Archdiocese of Italy (and Malta from 2005 until the creation of the Exarchate of Malta in 2021), officially the Sacred Orthodox Archdiocese of Italy and Exarchate of Southern Europe (Italian: Sacra Arcidiocesi Ortodossa d'Italia ed Esarcato per l'Europa Meridionale), is a diocese of the Ecumenical Patriarchate of Constantinople with its see in Venice. The diocese was created in 1991.
The current archbishop and exarch is Polykarpos Stavropoulos.
Greeks in Italy have been present since the migrations of traders and colonial foundations in the 8th century BC, continuing down to the present time. Nowadays, there is an ethnic minority known as the Griko people, who live in the Southern Italian regions of Calabria (Province of Reggio Calabria) and Apulia, especially the peninsula of Salento, within the ancient Magna Graecia region, who speak a distinctive dialect of Greek called Griko. They are believed to be remnants of the ancient and medieval Greek communities, who have lived in the south of Italy for centuries. A Greek community has long existed in Venice as well, the current centre of the Greek Orthodox Archdiocese of Italy and Malta, which in addition was a Byzantine province until the 10th century and held territory in Morea and Crete until the 17th century. Alongside this group, a smaller number of more recent migrants from Greece lives in Italy, forming an expatriate community in the country. Today many Greeks in Southern Italy follow Italian customs and culture, experiencing cultural assimilation.
