A Streetcar Named Desire is a 1951 American Southern Gothic drama film adapted from Tennessee Williams's Pulitzer Prize-winning play of the same name. Directed by Elia Kazan, it stars Vivien Leigh, Marlon Brando, Kim Hunter, and Karl Malden. The film tells the story of a Mississippi Southern belle, Blanche DuBois (Leigh), who, after encountering a series of personal losses, seeks refuge with her sister (Hunter) and brother-in-law (Brando) in a dilapidated New Orleans apartment building. The original Broadway production and cast was converted to film, albeit with several changes and sanitizations related to censorship.

Tennessee Williams collaborated with Oscar Saul and Elia Kazan on the screenplay. Kazan, who directed the Broadway stage production, also directed the black-and-white film. Brando, Hunter, and Malden all reprised their original Broadway roles. Although Jessica Tandy originated the role of Blanche DuBois on Broadway, Vivien Leigh, who had appeared in the London theatre production, was cast in the film adaptation for her star power. The film brought Brando, previously virtually unknown, to prominence as a major Hollywood film star, and earned him the first of four consecutive Academy Award nominations for Best Actor; Leigh won her second Academy Award for Best Actress for her portrayal of Blanche. It received Oscar nominations in ten other categories (including Best Picture, Best Director, and Best Adapted Screenplay), and won Best Supporting Actor (Malden), Best Supporting Actress (Hunter), and Best Art Direction (Richard Day, George James Hopkins), making it the first film to win in three of the acting categories.

The film earned an estimated $4,250,000 at the US and Canadian box office in 1951, making it the fifth biggest hit of the year. In 1999, A Streetcar Named Desire was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
