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

The film features the voices of Michèle Caucheteux, Jean-Claude Donda, Michel Robin, and Monica Viegas; there is little dialogue, the majority of the film story being told 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. She is joined by the Triplets of Belleville, music hall singers from the 1930s, whom she meets in the city, and her obese hound, Bruno.

The film was highly praised by audiences and critics for its unique (and somewhat retro) style of animation. 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.
