One Flew Over the Cuckoo's Nest (novel)

One Flew Over the Cuckoo's Nest is a novel by Ken Kesey published in 1962. Set in an Oregon psychiatric hospital, the narrative serves as a study of institutional processes and the human mind, including a critique of psychiatry and a tribute to individualistic principles. It was adapted into the Broadway (and later off-Broadway) play One Flew Over the Cuckoo's Nest by Dale Wasserman in 1963. Bo Goldman adapted the novel into a 1975 film of the same name directed by Miloš Forman, which won five Academy Awards.

Time magazine included the novel in its "100 Best English-language Novels from 1923 to 2005" list. In 2003 the book was listed on the BBC's The Big Read poll of the UK's 200 "best-loved novels."
