The Istanbul Greek dialect (Greek: Πολίτικη διάλεκτος or Κωνσταντινουπολίτικη διάλεκτος) is the endangered^[1] Greek dialect spoken by the Greek community in Istanbul, which has now shrunk to a couple thousand individuals. It is differentiated from Standard Greek due to a number of internal divergent developments, preservation of characteristics of Ancient Greek that are absent from Standard Greek, and language contact, most notably with Turkish, French, Italian and Armenian.^[1] Various characteristics of Istanbul Greek are said to have parallels in Old Athenian Greek, as well as Tsakonian.

The idiom is spoken mainly in Istanbul, and among the Istanbul Greek emigre community in Athens.
