Shanghai Noon is a 2000 American martial arts western action comedy film directed by Tom Dey in his feature film debut, written by Alfred Gough and Miles Millar, and starring Jackie Chan, Owen Wilson and Lucy Liu. It is the first entry in the Shanghai film series.

The film, set in Nevada and other parts of the American West in the 19th century, is a juxtaposition of a Western with a kung fu action film with extended martial arts sequences, as reflected by its title, which is a wordplay on the notable western High Noon. It also has elements of slapstick comedy and the "buddy film" genre, featuring two vastly different heroes (a Chinese Imperial Guard and an American Western outlaw) who team up to stop a crime.

The film premiered in Malaysia in May 19, 2000 and was released in the United States on May 26, 2000. It received generally positive from critics. A sequel, Shanghai Knights, was released in 2003, with Chan and Wilson reprising their roles.
