Carol is a 2015 historical romantic drama film directed by Todd Haynes. The screenplay by Phyllis Nagy is based on the 1952 romance novel The Price of Salt by Patricia Highsmith (republished as Carol in 1990). The film stars Cate Blanchett, Rooney Mara, Sarah Paulson, Jake Lacy, and Kyle Chandler. Set in 1950s New York City, the story is about a forbidden affair between an aspiring female photographer and an older woman going through a difficult divorce.

Carol was in development since 1997, when Nagy wrote the first draft of the screenplay. British company Film4 Productions and its then-chief executive Tessa Ross financed development. The film was in development hell, facing problems with financing, rights, scheduling conflicts, and accessibility. Number 9 Films came on board as a producer in 2011, when Elizabeth Karlsen secured the rights to the novel. The film is co-produced by New York–based Killer Films, which joined the project in 2013 after Haynes's collaborator Christine Vachon approached him to direct. Principal photography on the British-American production began in March 2014, in Cincinnati, Ohio, and lasted 34 days. Cinematographer Edward Lachman shot Carol on Super 16 mm film.

Carol premiered at the Cannes Film Festival on May 17, 2015, and was released in the United States on November 20 and in the United Kingdom on November 27. Grossing over $42 million on an $11 million budget, the film received widespread acclaim for Haynes's direction and the performances of Blanchett and Mara, and was the best-reviewed film of 2015. It competed for the Palme d'Or at Cannes, where Mara tied with Emmanuelle Bercot for the Best Actress award. The film received many accolades, including nominations for six Academy Awards, nine BAFTA Awards, and five Golden Globe Awards. It also won five Dorian Awards and awards from the New York Film Critics Circle, Los Angeles Film Critics Association, and National Society of Film Critics. Carol was ranked by the British Film Institute as the best LGBTQ film of all time, and named one of the greatest films of the 21st Century by the BBC.
