Double Crime in the Maginot Line (French: Double crime sur la ligne Maginot) is a 1937 mystery crime film directed by Félix Gandéra and starring Victor Francen, Véra Korène and Jacques Baumer.

The film's sets were designed by the art director Robert Gys.

It was a popular success, partly due to increasing concerns about a future war with Nazi Germany.

[3] While serving in the Maginot Line, the great fortifications along the border with Germany designed to deter an invasion, Captain Bruchot quarrels with his superior Commandant D'Espinac.

It appears that only three other men could possibly have committed the crime, one of whom may be a German secret agent.
