"The Exorcist" is a 1973 American supernatural horror film adapted by William Peter Blatty from his 1971 novel. The film is directed by William Friedkin and stars Ellen Burstyn, Linda Blair, Max von Sydow, and Jason Miller. It is the first film in the Exorcist series, and follows the demonic possession of a 12-year-old girl and her mother's attempt to rescue her through an exorcism conducted by two priests.

The cultural conversation around the film, which also encompassed its treatment of Roman Catholicism, helped it become the first horror film to be nominated for the Academy Award for Best Picture, one of ten Oscars it was nominated for, with Blatty's script and the film's sound winning their categories. It has remained high in critical esteem and commercial success ever since, becoming one of the highest-grossing films in history with a $441 million take as of 2019. For many years after its release it remained the top grosser in the supernatural horror and R-rated horror subcategories, as well.
