Kurt Kren (September 20, 1929 - died in Vienna on June 23, 1998) 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.
