Euphratensis (Latin for "Euphratean";Ancient Greek:Εὑφρατησία,Euphratēsía), fullyAugusta Euphratensis, was a late Roman and thenByzantine province inSyrian region, part of the ByzantineDiocese of the East.
Sometime between 330 and 350 AD (likelyc. 341), the Roman province ofEuphratensis was created out of the territory ofCoele Syria along the western bank of theEuphrates.[1] It included the territories ofCommagene andCyrrhestice. Its capital wasCyrrus[2] or perhapsHierapolis Bambyce.[1] It remained within the Byzantine Empire following the 395 division of the empire byTheodosius I.
The province is listed in theLaterculus Veronensis from around 314.
The Roman Catholic and Orthodox saintsSergius and Bacchus were supposedly martyred in the city ofResafa in Euphratensis, and the city was later renamed Sergiopolis. Other cities in the province wereSamosata andZeugma.
