Greifswald (German pronunciation: [ˈɡʁaɪfsvalt] ; Low German: Griepswold), officially the University and Hanseatic City of Greifswald (German: Universitäts- und Hansestadt Greifswald) is the fourth-largest city in the German state of Mecklenburg-Western Pomerania after Rostock, Schwerin and Neubrandenburg. In 2021 it surpassed Stralsund for the first time, and became the largest city in the Pomeranian part of the state. It sits on the River Ryck, at its mouth into the Danish Wiek, a sub-bay of the Bay of Greifswald, which is itself a sub-bay of the Bay of Pomerania of the Baltic Sea.
It is the seat of the district of Western Pomerania-Greifswald, and is located roughly in the middle between the two largest Pomeranian islands of Rügen and Usedom. The closest larger cities are Stralsund, Rostock, Szczecin and Schwerin. It lies west of the River Zarow, the historical cultural and linguistic boundary between West (west of the river) and Central Pomerania (east of the river). The city derives its name from the dukes of Pomerania, the House of Griffin, and thus ultimately from the Pomeranian Griffin, and its name hence translates as "Griffin's Forest".
