A Clockwork Orange (1962) is a dystopian novel by Anthony Burgess.

The title is taken from an old Cockney expression, "as queer as a clockwork orange", and alludes to the prevention of the main character's exercise of his free will through the use of a classical conditioning technique. With this technique, the subject’s emotional responses to violence are systematically paired with a negative stimulation in the form of nausea caused by an emetic medicine administered just before the presentation of films depicting "ultra-violent" situations. Written from the perspective of a seemingly biased and unapologetic protagonist, the novel also contains an experiment in language: Burgess creates a new speech that is the teenage slang of the not-too-distant future.

The novel has been adapted for cinema by Stanley Kubrick and Andy Warhol; adaptations have also been made for television and the stage. As well as inspiring a concept album, the novel and films are referred to in and have inspired a number of songs.
