Triumph of the Will (German: Triumph des Willens) is a 1935 German propaganda film directed; produced; edited; and co-written by Leni Riefenstahl. It chronicles the 1934 Nazi Party Congress in Nuremberg; which was attended by more than 700;000 Nazi supporters.

The film contains excerpts from speeches given by Nazi leaders at the Congress; including Adolf Hitler; Rudolf Hess; and Julius Streicher; interspersed with footage of massed Sturmabteilung and Schutzstaffel troops and public reaction.

Hitler commissioned the film and served as an unofficial executive producer; his name appears in the opening titles. The film's overriding theme is the return of Germany as a great power; with Hitler as the leader who will bring glory to the nation.
