Farther Pomerania, Further Pomerania, Transpomerania or Eastern Pomerania , is the part of Pomerania which comprised the eastern part of the Duchy and later Province of Pomerania. It stretched roughly from the Oder River in the West to Pomerelia in the East. Since 1945 Farther Pomerania has been part of Poland; the bulk of former Farther Pomerania is within the West Pomeranian Voivodeship, while its easternmost parts are within the Pomeranian Voivodeship. The Polish term Pomorze Zachodnie ("Western Pomerania"), in modern Polish usage, is a synonym to the West Pomeranian Voivodship; in Polish historical usage it applied to all areas west of Pomerelia (i.e. whole narrow Pomerania).
