Shanghai Noon is a 2000 American martial arts western action comedy film starring Jackie Chan, Owen Wilson and Lucy Liu. The first in the Shanghai film series and marking the directorial debut of Tom Dey, Shanghai Noon was written by Alfred Gough and Miles Millar. The film received positive reviews and was a commercial success.

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 comedy and the "Buddy cop film" genre, featuring two vastly different heroes (a Chinese Imperial Guard and an American Western outlaw) who team up to stop a crime. It is reminiscent of the drama film of the genre from which it is largely inspired: Red Sun, with Charles Bronson (Wanted Cowboy) and Toshiro Mifune (Imperial Samuraï), but in the comedy register.It was partially filmed in the Canadian Badlands, near Drumheller, Alberta, Canada, near Exshaw, Alberta, and also near Cochrane, Alberta.

A sequel, Shanghai Knights, was released in 2003, with David Dobkin as director.
