Doctor Sleep is a 2019 American supernatural horror film written, directed, and edited by Mike Flanagan. It is an adaptation of the 2013 novel of the same name by Stephen King and sequel to Stanley Kubrick's 1980 film The Shining. The film stars Ewan McGregor as Dan Torrance, a man with psychic abilities and a drinking problem, who struggles with childhood trauma caused by the horrors at the Overlook Hotel. Rebecca Ferguson, Kyliegh Curran, and Cliff Curtis have supporting roles as new characters: Abra Stone and Billy Freeman team up with Dan to take down Rose the Hat and her gang of followers.

Warner Bros. Pictures began developing a film adaptation shortly after Doctor Sleep was published in 2013. Writer-producer Akiva Goldsman wrote a script, but the studio did not secure a budget for the film until the box office success of its 2017 horror film It, also based on a novel by King. Flanagan was hired to rewrite Goldsman's script and direct the Doctor Sleep film. Flanagan said he wanted to reconcile the differences between The Shining novel and film. Filming began in September 2018 in Georgia, including Atlanta and the surrounding area, and concluded that December.

Doctor Sleep held its world premiere at the Regency Village Theater in Los Angeles on October 21, 2019, and was theatrically released worldwide on October 31, 2019, and in the United States on November 8. The film received generally positive reviews from critics, who praised Flanagan's direction and screenplay, and the performances of the cast (especially McGregor, Ferguson, and Curran) but criticized its runtime. Grossing $72.4 million worldwide, its performance at the box office was considered a disappointment compared to the other King adaptations released in 2019: It Chapter Two and Pet Sematary.
