Albanians in Greece (Albanian: Shqiptarët në Greqi, Greek: Αλβανικές κοινότητες στην Ελλάδα) are divided into distinct communities as a result of different waves of migration. Albanians first migrated into Greece during the late Middle Ages (late 13th century). The descendants of populations of Albanian origin who settled in Greece during the Middle Ages are the Arvanites, who have been fully assimilated into the Greek nation and self-identify as Greeks. Today, they still maintain their distinct subdialect of Tosk Albanian, known as Arvanitika.
