The Letterenhuis ("House of Literature") is a Belgian non-profit organization located in Antwerp. The Letterenhuis collects and archives information of Flemish writers and artists, and portraits concerning Flemish culture as from 1750. The Letterenhuis fulfills two tasks: on the one hand it is an archiving and documentation centre and on the other hand it is a museum.
The organization was founded in 1933 as the Museum van de Vlaamsche Letterkunde ("Museum of Flemish Literature").
