The Province of Pomerania was a province of Brandenburg-Prussia, the later Kingdom of Prussia. After the Thirty Years' War, the province consisted of Farther Pomerania. Subsequently, the Lauenburg and Bütow Land, Draheim, and Swedish Pomerania south of the Peene river were joined into the province. The province was succeeded by the Province of Pomerania set up in 1815.

Brandenburg-Prussia is the historiographic denomination for the early modern realm of the Brandenburgian Hohenzollerns between 1618 and 1701. Based in the Electorate of Brandenburg, the main branch of the Hohenzollern intermarried with the branch ruling the Duchy of Prussia, and secured succession upon the latter's extinction in the male line in 1618. Another consequence of intermarriage was the incorporation of the lower Rhenish principalities of Cleves, Mark and Ravensberg after the Treaty of Xanten in 1614.
