This article is about the Greek communities after the establishment of the Republic of Turkey, in 1923. For the pre-1923 Greek communities see: History of Anatolia#Classical Antiquity, Byzantine Empire, Ottoman Greeks, Pontic Greeks, Eastern Anatolia Greeks, and Caucasus Greeks.

The Greeks in Turkey constitute a population of Greek and Greek-speaking Eastern Orthodox Christians who mostly live in Istanbul, as well as on the two islands of the western entrance to the Dardanelles: Imbros and Tenedos ( and Bozcaada).
