Darmstädter Ferienkurse is a regular summer event of contemporary classical music in Darmstadt, Hesse, Germany. It was founded in 1946, under the name "Ferienkurse für Internationale Neue Musik Darmstadt", as a gathering with lectures and concerts over several summer weeks. Composers, performers, theorists and philosophers of contemporary music met first annually until 1970, and then biennially. The event was organised by the Kranichsteiner Musikinstitut, which was renamed Internationales Musikinstitut Darmstadt (IMD). It is regarded as a leading international forum of contemporary and experimental music with a focus on composition. The festival awards the Kranichsteiner Musikpreis for performers and young composers.

Wolfgang Fortner was a German composer, academic composition teacher and conductor.
