The King of Comedy is a 1982 American satirical black comedy film directed by Martin Scorsese and starring Robert De Niro (in his fifth collaboration with Scorsese), Jerry Lewis and Sandra Bernhard. Written by Paul D. Zimmerman, the film focuses on themes such as celebrity worship and American media culture. 20th Century-Fox released the film on February 18, 1983, in the United States, though the film was released two months earlier in Iceland.

In the film, an aspiring stand-up comedian is increasingly obsessed with a successful comedian whom he met by chance.

Production began in New York on June 1, 1981, to avoid clashing with a forthcoming writers' strike, and opened at the Cannes Film Festival in 1983. The film received mostly positive reviews from critics but was a flop at the box office, grossing only $2.5 million against its $19 million budget. It is the first production of Embassy International Pictures, later Regency Enterprises.
