The Duellists is a 1977 British period drama film directed by Ridley Scott and produced by David Puttnam. Set in France during the Napoleonic Wars, the film focuses on a series of duels between two rival officers, the obsessive Bonapartist Gabriel Feraud (played by Harvey Keitel) and aristocratic Armand d'Hubert (Keith Carradine), that spans nearly 20 years and reflects the political tumult of early 19th-century France. The film is based on Joseph Conrad's short story "The Duel" (titled "Point of Honor" in the United States), first published in A Set of Six.

Scott's feature directorial debut, the film unanimously won the award for Best Debut Film at the 1977 Cannes Film Festival, and was nominated for the Palme d'Or. The Duellists earned widespread acclaim from critics, who praised Scott's direction and visuals, and the film's historical authenticity. The fight choreography, by master swordsman William Hobbs, is considered one of the most accurate depictions of dueling in film. At the 32nd British Academy Film Awards, the film received BAFTA nominations for Best Cinematography and Best Costume Design.
