The Bourne Supremacy is a 2004 spy mystery thriller film loosely based on the Robert Ludlum novel of the same name. The film was directed by Paul Greengrass, written by Tony Gilroy and Brian HelgelandThe Bourne Supremacy (2004) and produced by Doug Liman and Frank Marshall. Universal Studios released the film to theaters in the United States on July 23, 2004 and it received a positive critical and public reaction similar to its predecessor, The Bourne Identity. The film is followed by a 2007 sequel entitled The Bourne Ultimatum.

It is also the sequel to the 2002 film The Bourne Identity and the second film of the Bourne Trilogy. The Bourne Supremacy continues the story of Jason Bourne, an amnesiac and former CIA assassin played by Matt Damon, and his attempt to learn more of his shadowy past as he is once more enveloped in a conspiracy surrounding the CIA and Operation Treadstone. The film also stars Franka Potente as Marie Helena Kreutz, Brian Cox as Ward Abbott, Joan Allen as Pamela Landy and Julia Stiles as Nicolette Parsons.

It substantially deviates from its source material as Alexander Conklin is now dead and the CIA is Bourne's enemy rather than his friend (the plot actually incorporates aspects of the Bourne novel The Bourne Legacy written by Eric Van Lustbader as well). In addition, the book's narrative takes place in Hong Kong with Marie getting kidnapped so Bourne will accept a mission.
