Three Colours: Red (French: Trois couleurs: Rouge, Polish: Trzy kolory: Czerwony) is a 1994 drama film co-written, produced and directed by Polish filmmaker Krzysztof Kieślowski. It is the final installment of the Three Colours trilogy, which examines the French Revolutionary ideals; it is preceded by Blue and then by White. Kieślowski had announced that this would be his final film, planning to retire claiming to be through with filmmaking; he would die suddenly less than two years later. Red is about fraternity, which it examines by showing characters whose lives gradually become closely interconnected, with bonds forming between two characters who appear to have little in common.

Red was released to universal critical acclaim and was nominated for three Academy Awards, including Best Director for Kieślowski. It was also selected as the Swiss entry for the Best Foreign Language Film at the 67th Academy Awards, but was disqualified for not being a majority-Swiss production; its precedent however, submitted by Poland, was accepted although it did not secure a nomination. Since then it has been widely regarded as the best film of the trilogy, Kieślowski's magnum opus, one of the best films of all time, as well as one of the greatest French-language films ever made.
