Ellinochori (Greek: Ελληνοχώρι meaning Greek town; formerly Βουλγάρκιοϊ,Bulgarian: Булгаркьой or Балъ Булгаркьой, Turkish: Bulgarkoj or Balı-Bulgarköy, Bulgarian village) is a village in the northeastern part of the Evros regional unit in Greece. Ellinochori is part of the municipality of Didymoteicho. It is situated on the left bank of the river Erythropotamos, northwest of the centre of Didymoteicho. In 2001 its population was 756 for the village and 2,372 for the municipal district, including the villages Lagos and Thyrea.
The village was founded by the Ottoman Turks and named after its mostly Bulgarian population. It was ceded to Bulgaria in 1915 along with the rest of the lower Evros (Maritsa) valley, but following the 1919 Treaty of Neuilly it became part of Greece. As a result its Bulgarian and Turkish population was exchanged with Greek refugees, mainly from today's Turkey.
