A.I. Artificial Intelligence (or simply A.I.) is a 2001 American science fiction film directed by Steven Spielberg. The screenplay by Spielberg and screen story by Ian Watson were based on the 1969 short story "Supertoys Last All Summer Long" by Brian Aldiss. Set in a futuristic post-climate change society, the film stars Haley Joel Osment as David, a childlike android uniquely programmed with the ability to love. Jude Law, Frances O'Connor, Brendan Gleeson, and William Hurt star in supporting roles.

Development of A.I. originally began after producer/director Stanley Kubrick acquired the rights to Aldiss' story in the early 1970s. Kubrick hired a series of writers, including Brian Aldiss, Bob Shaw, Ian Watson, and Sara Maitland, until the mid-1990s. The film languished in development hell for years, partly because Kubrick felt that computer-generated imagery was not advanced enough to create the David character, whom he believed no child actor would convincingly portray. In 1995, Kubrick handed A.I. to Spielberg, but the film did not gain momentum until Kubrick died in 1999. Spielberg remained close to Watson's treatment for the screenplay, and dedicated the film to Kubrick.

A.I. Artificial Intelligence was released on June 29, 2001 by Warner Bros. Pictures in North America and by DreamWorks Pictures internationally. It received generally positive reviews from critics and grossed $235.9 million against a budget of $90–100 million. It was also nominated for Best Visual Effects and Best Original Score (for John Williams) at the 74th Academy Awards. In a 2016 BBC poll of 177 critics around the world, A.I. Artificial Intelligence was voted the eighty-third greatest film since 2000. It has since been called one of Spielberg's best works and one of the greatest films of the 2000s and of the 21st century.
