The Bay of Pomerania or Pomeranian Bay (Polish: Zatoka Pomorska; German: Pommersche Bucht; Kashubian: Pòmòrskô Hôwinga) is a basin in the southwestern Baltic Sea, off the shores of Poland and Germany.

In the south it is separated from the Oder Lagoon in the mouth of the Oder River by the islands of Usedom/Uznam and Wolin, connected by three straits or branches of the Oder: Dziwna, Świna and Peene. North border is a line from Cape Arkona on the German island of Rügen to the Gąski Lighthouse in the east of Kołobrzeg in Poland.

Maximum depth is 20 metres and salinity is about 8‰. The bay of Pomerania is crossed by a deepened waterway from the Szczecin seaport, via the river Oder, the Szczecin Lagoon, and Świna allowing large ships to enter the ports of Świnoujście and Szczecin.

Main ports are:

Pomerania - Polish: Pomorze, Kashubian: Pòmòrze or Pòmòrskô, (German: Pommern, Latin: Pomerania or Pomorania) is a historical region on the south shore of the Baltic Sea. Divided between Germany and Poland, it stretches roughly from the Recknitz River near Stralsund in the West, via the Oder River delta near Szczecin, to the mouth of the Vistula River near Gdańsk in the East. Pomerania was strongly affected by 20th century, post-World War I and II border and population shifts.

Pomerania belongs to the lowlands of the North European Plain. Outside its few urban centers − most notably the Szczecin and Tricity metropolitan areas − the poor soil is mostly used as farmland, dotted with numerous lakes, forests, and small towns. Agriculture primarily consists of raising livestock, forestry, fishery and the cultivation of cereals, sugar beets, and potatoes. Since the late 19th century, tourism has become an important sector of the economy, primarily in the numerous seaside resorts along the coast. Of the limited industrial zones, the most important products are ships, metal products, refined sugar, and paper.
