Stanley Kubrick (; July 26, 1928 – March 7, 1999) was an American film director, producer and screenwriter. Widely considered one of the greatest filmmakers of all time, his films—almost all of which are adaptations of novels or short stories—cover a wide range of genres and feature innovative cinematography, dark humor, realistic attention to detail and extensive set designs.

Kubrick was raised in the Bronx, New York City, and attended William Howard Taft High School from 1941 to 1945. He received average grades but displayed a keen interest in literature, photography, and film from a young age, and taught himself all aspects of film production and directing after graduating from high school. After working as a photographer for Look magazine in the late 1940s and early 1950s, he began making short films on shoestring budgets, and made his first major Hollywood film, The Killing, for United Artists in 1956. This was followed by two collaborations with Kirk Douglas: the war picture Paths of Glory (1957) and the historical epic Spartacus (1960).

Creative differences arising from his work with Douglas and the film studios, a dislike of the Hollywood industry, and a growing concern about crime in America prompted Kubrick to move to the United Kingdom in 1961, where he spent most of his remaining life and career. His home at Childwickbury Manor in Hertfordshire, which he shared with his wife Christiane, became his workplace, where he did his writing, research, editing, and management of production details. This allowed him to have almost complete artistic control over his films, but with the rare advantage of having financial support from major Hollywood studios. His first productions in Britain were two films with Peter Sellers: Lolita (1962), an adaptation of the novel by Vladimir Nabokov, and the Cold War black comedy Dr. Strangelove (1964).

A demanding perfectionist, Kubrick assumed control over most aspects of the filmmaking process, from direction and writing to editing, and took painstaking care with researching his films and staging scenes, working in close coordination with his actors, crew, and other collaborators. He often asked for several dozen retakes of the same shot in a movie, which resulted in many conflicts with his casts. Despite the resulting notoriety among actors, many of Kubrick's films broke new ground in cinematography. The scientific realism and innovative special effects of the science fiction epic 2001: A Space Odyssey (1968) were without precedent in the history of cinema, and the film earned him his only personal Oscar, for Best Visual Effects. Steven Spielberg has referred to the film as his generation's "big bang"; it is regarded as one of the greatest films ever made.

While many of Kubrick's films were controversial and initially received mixed reviews upon release—particularly the brutal A Clockwork Orange (1971), which Kubrick pulled from circulation in the UK following a mass media frenzy—most were nominated for Oscars, Golden Globes, or BAFTA Awards, and underwent critical reevaluations. For the 18th-century period film Barry Lyndon (1975), Kubrick obtained lenses developed by Zeiss for NASA, to film scenes under natural candlelight. With the horror film The Shining (1980), he became one of the first directors to make use of a Steadicam for stabilized and fluid tracking shots, a technology vital to his Vietnam War film Full Metal Jacket (1987). His last film, Eyes Wide Shut, was completed shortly before his death in 1999 at the age of 70.
