Code of Silence is a 1985 American action thriller film directed by Andrew Davis and starring Chuck Norris, Henry Silva, Dennis Farina and Molly Hagan. It was released in the United States on May 3, 1985.It was an atypical film for Norris, whose previous ones had been known more for his martial arts skills. A crime drama, it was filmed on location in Chicago with a few subplots. It features Norris as Sgt. Eddie Cusack, a streetwise plainclothes officer who takes down a crime czar responsible for officers being wounded in a botched drug raid. In the film's climax, Norris teams up with a crime-fighting robot named "Prowler."

Dennis Farina was an actual Chicago police officer during the making of this film, moonlighting before becoming a full-time actor when cast in the leading role of Michael Mann's 1986 television series Crime Story.

Davis said the film "made a lot of money and I got pegged as an action director."
