The Friends of the Museum für Kunst und Kultur Münster has been supporting the institution since 1976. Each year the Friends purchase works of art for the collections from membership fees and individual donations. A unique feature is that members can vote in acquisition meetings on which works are to be purchased.

Young Friends has been in existence since 2005, which is targeted at trainees and young families, higher education students, young professionals and all young people interested in actively experiencing culture.
