Contraband (1940) is a wartime spy film by the British director-writer team of Michael Powell and Emeric Pressburger, which reunited stars Conrad Veidt and Valerie Hobson after their earlier appearance in The Spy in Black the previous year. On this occasion, Veidt plays a hero, something he did not do very often, and there is also an early (uncredited) performance by Leo Genn.

The title of the film in the United States was Blackout. Powell writes in his autobiography, A Life in Movies, as saying that the U.S. renaming was a better title and he wished he had thought of it.
