4Θ Ekklisies (Greek: Σαράντα Εκκλησιές "Forty Churches") is a neighbourhood in Thessaloniki, Greece. It is located next to the Ano Poli.

It was created in the 1920s during the Greek-Turkish population exchange by Greek refugees from the city of Saranta Ekklisies (currently known as Kırklareli) in Eastern Thrace.^[1]

The central street was constructed in 1940. Beside the area there was the Jewish cemetery.
