Museumshaus, Historical museum in Mecklenburg-Western Pomerania, Germany.

The Museumshaus at Mönchstraße 38 is a two-storey gabled brick house built in the 14th century as a Krämerhaus, one of Stralsund's oldest burgher houses. Its roof structure dates to the years just after 1300 and survives almost complete; Gothic brick pilasters on the street gable, the courtyard gable and the hoist wheel remain. Two Utluchten bay windows were added in the 18th century.

Built in the 14th century as a Krämerhaus (merchant's house), Mönchstraße 38 is one of Stralsund's oldest burgher houses. Its roof structure dates to the years just after 1300 and came from a wooden predecessor with half-timbered gables. Alterations followed in the 17th and 19th centuries, and the Deutsche Stiftung Denkmalschutz restored the building from 1996 to 1999.

The house is called Museumshaus because the Stralsund Museum has used it since its 1996–1999 restoration by the Deutsche Stiftung Denkmalschutz. Inside, the exhibition shows furniture from the museum's collection and finds uncovered during the restoration work. Shops occupy the two 18th-century Utluchten projecting from the facade.

The house is an outbuilding of the Stralsund Museum and can be visited from the Kaufkeller up to the roof; a short film documents the 1996–1999 restoration by the Deutsche Stiftung Denkmalschutz. Shops occupy the two 18th-century Utluchten projecting from the facade.

The roof structure dates to the first years after 1300 and came from a wooden predecessor building with half-timbered gables; it survives almost complete. In 2024 the historian Andrew Wallis revealed that SS leader Herbert Lange spent his youth in this house.
