Hamlet is a 1948 British film adaptation of William Shakespeare's play of the same name, adapted and directed by and starring Laurence Olivier. Hamlet was Olivier's second film as director and the second of the three Shakespeare films that he directed (the 1936 As You Like It had starred Olivier, but had been directed by Paul Czinner). Hamlet was the first British film to win the Academy Award for Best Picture. It is the first sound film of the play in English.

Olivier's Hamlet is the Shakespeare film that has received the most prestigious accolades, winning the Academy Awards for Best Picture and Best Actor and the Golden Lion at the Venice Film Festival. However, it proved controversial among Shakespearean purists, who felt that Olivier had made too many alterations and excisions to the four-hour play by cutting one-and-a-half-hours' worth of content. Milton Shulman wrote in The Evening Standard: "To some it will be one of the greatest films ever made, to others a deep disappointment. Laurence Olivier leaves no doubt that he is one of our greatest living actors... his liberties with the text, however, are sure to disturb many."
