Naked Lunch (sometimes The Naked Lunch) is a 1959 novel by American writer William S. Burroughs. The book is structured as a series of loosely connected vignettes, intended by Burroughs to be read in any order. The reader follows the narration of junkie William Lee, who takes on various aliases, from the U.S. to Mexico, eventually to Tangier and the dreamlike Interzone.

The vignettes (which Burroughs called "routines") are drawn from Burroughs' own experiences in these places and his addiction to drugs: heroin, morphine and, while in Tangier, majoun (a strong hashish confection), as well as a German opioid with the brand name Eukodol (oxycodone), of which he wrote frequently.

The novel was included in Time 's "100 Best English-language Novels from 1923 to 2005". In 1991, David Cronenberg wrote and directed a film of the same name based on the novel and other Burroughs writings.
