Shanghai Noon is a 2000 American-Hong Kong action comedy western film starring Jackie Chan, Owen Wilson and Lucy Liu. The film, marking the directorial debut of Tom Dey, was written by Alfred Gough and Miles Millar.

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. It also has elements of comedy and the "Buddy Cop" film genre, as it involves two men of different personalities and ethnicities (a Chinese imperial guard and a white Western outlaw) who team up to stop a crime. It was partially filmed in the Canadian Badlands, near Drumheller, Alberta, Canada, and also near Cochrane, Alberta. A sequel, Shanghai Knights, was released in 2003, with David Dobkin as director.
