The Game of Death (Chinese: 死亡的遊戲) is an incomplete Hong Kong martial arts film, of which portions were filmed between September and October 1972, directed, written, produced by and starring Bruce Lee. The project was paused to film and produce Enter the Dragon. For The Game of Death, over 120 minutes of footage was shot. The remaining footage has since been released with Lee's original Cantonese and English dialogue, with John Little dubbing Lee's Hai Tien character as part of the documentary titled Bruce Lee: A Warrior's Journey. Much of the footage that was shot is from what was to be the climax of the film.

During filming, Lee received an offer to star in Enter the Dragon, the first kung fu film to be produced by a Hollywood studio (Warner Bros.), and with a budget unprecedented for the genre ($850,000). Lee died of cerebral edema before the film's release. At the time of his death, he had made plans to resume the filming of The Game of Death. After Lee's death, Enter the Dragon director Robert Clouse was enlisted to finish the film using two stand-ins; it was released in 1978 as Game of Death, five years after Lee's death, by Golden Harvest.

The story of Lee's original 1972 film involves Lee's character, in order to save his younger sister and brother, joining a group of martial artists who are hired to retrieve a stolen Chinese national treasure from the top floor of a five-story pagoda in South Korea, with each floor guarded by martial artists who must be defeated while ascending the tower. The 1978 film's plot was altered to a revenge story, where the mafia attempts to kill Lee's character, who fakes his death and seeks vengeance against those who tried to kill him. The final part of the film uses some of Lee's original film footage, but with the pagoda setting changed to a restaurant building, where he fights martial artists hired by the mafia in an attempt to rescue his fiancée Ann Morris (played by Colleen Camp). This revised version received a mixed critical reception but was commercially successful, grossing an estimated US$50,000,000 (equivalent to $230,000,000 in 2023) worldwide.

It was an influential film that had a significant cultural impact. The original version's concept of ascending a tower while defeating enemies on each level was highly influential, inspiring numerous action films and video games. The film is also known for Lee's iconic yellow-and-black jumpsuit as well as his fight scene with NBA player and student Kareem Abdul-Jabbar, both of which have been referenced in numerous media.
