Kurt Kren (born 20 September 1929; died 23 June 1998 in Vienna) was an Austrian avant-garde filmmaker. He is best known for his involvement with the Vienna Aktionists and the group of films that resulted, although this accounts for only a part of his career, and he later returned to the Structural roots of his third film 3/60: Bäume Im Herbst. Although not a seminal Structural film, 31/75: Asyl is arguably one of the more satisfying films of the movement.
