Pomeranian State Museum, Regional art and history museum in Greifswald, Germany.

The Pomeranian State Museum occupies four buildings linked by a glass hall on Greifswald's Mühlenstraße. Its main building, the former "Graues Kloster" workhouse, was built 1843–45; the late-Gothic monastery library and convent building stand beside it, and the 1793–97 Quistorp town school now holds the painting gallery. The permanent history exhibition spans three floors with about 2,500 objects.

The museum was built on the site of a medieval Franciscan monastery known as the Grey Monastery, founded in Greifswald during the 13th century. After the Reformation the monastery lost its religious role, and parts of the original structure, including the cloister library, were later incorporated into the museum building.

The gallery's holdings come mainly from two collections: the former Museum of the Hanseatic City of Greifswald and the rescued paintings of the Städtisches Museum für Kunst und Kunstgewerbe in Stettin. In 2024, for Friedrich's 250th birthday, the museum ran three successive special exhibitions on the Greifswald painter; in December 2025 the Galerie der Romantik opened in the Quistorp building, focused on his life and work.

The museum occupies four buildings linked by a glass hall, the so-called Museumsstraße, between Mühlenstraße and the town wall. The main building holds the three-floor permanent history exhibition; the late-Gothic monastery library and the former convent building stand on the east side of the hall, and the gallery is in the Quistorp building. Allow time to cross between them.

The museum's four buildings are linked by a glass hall called the Museumsstraße. The gallery building, erected 1793–97 to plans by painter Johann Gottfried Quistorp as the town school, was built from the bricks and partly on the foundations of the monastery church demolished in 1789. In December 2025 the Gallery of Romanticism opened there, centred on Caspar David Friedrich.
