The Bay of Greifswald or Greifswald Bodden (German: Greifswalder Bodden) is a basin in the southwestern Baltic Sea, off the shores of Germany in the state of Mecklenburg-Vorpommern. With an area of 514 km², it is the largest Bodden of the German Baltic coast. To the west is the island of Rügen; to the southeast, the island of Usedom; to the east, the Bay of Pomerania, and to the south, the German mainland. The bay is also joined to the Baltic Sea through the Strelasund, a narrow sound separating Rügen from the mainland. The bay's northern end is sometimes called the Rügischer Bodden. * Map * *
