Nea Erythraia (Greek: Νέα Ερυθραία) is a town and a suburb in the northeastern part of the Athens agglomeration, Greece. It was settled by Greek refugees from Erythraia (now Cesme, Turkey) after the 1923 Population Exchange. Since the 2011 local government reform it is part of the municipality Kifissia, of which it is a municipal unit.^[2]
