François Roland Truffaut (UK: TROO-foh, TRUU-, US: troo-FOH; French: [fʁɑ̃swa ʁɔlɑ̃ tʁyfo]; 6 February 1932 – 21 October 1984) was a French film director, screenwriter, producer, actor, and film critic. He is widely regarded as one of the founders of the French New Wave. After a career of more than 25 years, he remains an icon of the French film industry.

Truffaut's film The 400 Blows (1959) is a defining film of the French New Wave movement, and has four sequels, Antoine et Colette (1962), Stolen Kisses (1968), Bed and Board (1970), and Love on the Run (1979). Truffaut's 1973 film Day for Night earned him critical acclaim and several awards, including the BAFTA Award for Best Film and the Academy Award for Best Foreign Language Film. His other notable films include Shoot the Piano Player (1960), Jules and Jim (1962), The Soft Skin (1964), The Wild Child (1970), Two English Girls (1971), The Last Metro (1980), and The Woman Next Door (1981). He is also known for his supporting role in Steven Spielberg's science fiction film Close Encounters of the Third Kind (1977).

Truffaut also wrote the notable book Hitchcock/Truffaut (1966), which detailed his interviews with the film director Alfred Hitchcock during the 1960s.
