Thou Shalt Not Kill ... Except, also known as Stryker's War, is a 1985 American action horror film directed by Josh Becker and starring Robert Rickman, John Manfredi, Tim Quill, Cheryl Hausen, Perry Mallette and Sam Raimi. It was written by Becker and Scott Spiegel from a story by Becker, actor Bruce Campbell, and Sheldon Lettich.

The cast of the film consists largely of unknowns, because most of the smaller roles are filled by Becker's friends and relatives. Some, however, have been featured in other films, largely those produced by Renaissance Pictures or otherwise involving Sam Raimi, Bruce Campbell or Josh Becker.

The film held its premiere in Warren, Michigan on October 13, 1985, and was later released to video in West Germany and Japan on 21 May 1987, followed by Canada on March 31, 1999. The low budget film is fairly obscure, but maintains a small following as an underground cult classic.
