Thou Shalt Not Kill (French: Tu ne tueras point), also known as L'objecteur, is a 1961 French feature film directed by Claude Autant-Lara, written by Jean Aurenche and Pierre Bost, and starring Laurent Terzieff and Horst Frank.

It is about a conscientious objector (Laurent Terzieff), imprisoned and on hunger strike, because of his opposition to war.

Autant-Lara had trouble obtaining funding for the film, in part because of its anti-war message at the time of France's involvement in the Algerian War.

Bernard Dort, in one of the few positive reviews, noted that the film was more a study of its two main characters than an anti-war tirade.

[4] Suzanne Flon, playing the conscientious objector's mother, won the Volpi Cup at the 1961 Venice Film Festival for best actress.
