The Kurt Weill Foundation for Music, Inc. administers, promotes, and perpetuates the legacies of Kurt Weill and Lotte Lenya. It encourages broad dissemination and appreciation of Weill's music through support of performances, productions, recordings, and scholarship; it fosters understanding of Weill's and Lenya's lives and work within diverse cultural contexts; and, building upon the legacies of both, it nurtures talent, particularly in the creation, performance, and study of musical theater in its various manifestations and media.

The foundation administers the Weill-Lenya Research Center; a Grant Program, the Kurt Weill Book Prize and the Lotte Lenya Competition, and publishes the Kurt Weill Edition and the Kurt Weill Newsletter.
