Rumsko () is a village in the administrative district of Gmina Gà Âówczyce, within Sà Âupsk County, Pomeranian Voivodeship, in northern Poland. It is located in the historic region of Pomerania.
In the 960s the area became part of the emerging state of Poland. After the fragmentation of Poland into smaller duchies, it was at various times part of the duchies of Pomerania (Western), Pomerania (Eastern) and SÃ Âupsk. In 1648 it passed to Brandenburg, then in 1701 to Prussia, and in 1871 to the German Empire. Historically, it was also known in Polish as Rumska. Following Germany's defeat in World War II in 1945, it became again part of Poland.
