Pieces (Spanish: Mil gritos tiene la noche, lit. 'The Night Has 1,000 Screams') is a 1982 slasher film directed by Juan Piquer Simón, written and produced by Dick Randall, and starring Christopher George, Lynda Day George, Frank Braña, Edmund Purdom, Paul L. Smith, Ian Sera, and Jack Taylor. The plot follows an unknown assailant killing female students at a college campus in Boston, who uses their body parts to make a human jigsaw puzzle.

A co-production between Spain, Italy, the United States, and Puerto Rico, Pieces was filmed largely in Spain, with some location shooting in the Boston, Massachusetts area. It was released in Spain in August 1982, and was distributed in the United States the following year by Film Ventures International.

Since its release, the film has attracted a cult following and has been a drive-in favorite. While not prosecuted for obscenity, the film was seized and confiscated in the UK under Section 3 of the Obscene Publications Act 1959 during the video nasty controversy.
