5 Fingers, known also as Five Fingers, is a 1952 American spy film noir directed by Joseph L. Mankiewicz and produced by Otto Lang. The screenplay written by Michael Wilson was based on the 1950 book Operation Cicero (original German: Der Fall Cicero) by Ludwig Carl Moyzisch, Nazi commercial attaché at the German embassy in Ankara, Turkey (1943–44).

The film is based on the true story of Albanian-born Elyesa Bazna, a spy with the code name of Cicero who worked for the Nazis in 1943–44 while he was employed as valet to the British ambassador to Turkey, Sir Hughe Montgomery Knatchbull-Hugessen. Bazna would photograph top-secret documents and deliver the pictures to Franz von Papen, the German ambassador in Turkey and a former German chancellor, using Moyzisch as the intermediary.

James Mason plays Ulysses Diello (Cicero), the character based on Bazna. The film also stars Danielle Darrieux, Michael Rennie, Herbert Berghof and Walter Hampden.
