The Triplets of Belleville (French: Les Triplettes de Belleville) is a 2003 animated adventure comedy-drama film written and directed by Sylvain Chomet. It was released as Belleville Rendez-vous in the United Kingdom and Ireland. The film is Chomet's first feature film and was an international co-production among companies in France, Belgium, Canada and the United Kingdom.

The film features the voices of Lina Boudreault, Mari-Lou Gauthier, Michèle Caucheteux, Jean-Claude Donda, Michel Robin, and Monica Viegas. There is little dialogue; much of the narrative is conveyed through song and pantomime. It tells the story of Madame Souza, an elderly woman who goes on a quest to rescue her grandson Champion, a Tour de France cyclist, who has been kidnapped by the French mafia for gambling purposes and taken to the city of Belleville (an amalgamation of Paris, New York City, Montreal and Quebec City). She is accompanied by Champion's loyal and obese hound, Bruno, and joined by the Triplets of Belleville, music hall singers from the 1930s, whom she meets in the city.

The film was highly praised by audiences and critics for its unique style of animation and has since gained a cult following. The film was nominated for two Academy Awards—Best Animated Feature and Best Original Song for "Belleville Rendez-vous". It was also screened out of competition (hors concours) at the 2003 Cannes Film Festival.
