Code Unknown (French: Code inconnu : Récit incomplet de divers voyages) is a 2000 film directed by Michael Haneke. Most of the story occurs in Paris, France, where the fates of several characters intersect and connect.

Code Unknown is composed of unedited long takes filmed in real time, cut only when the perspective within a scene changes from one character's to another's in the middle of the action. A special edition of the film was released on Blu-ray in 2015 by The Criterion Collection. The film is inspired by the life of the French novelist and war reporter Olivier Weber.

Code Unknown is a co-production among France, Germany and Romania.
