Bad Lieutenant: Port of Call New Orleans is a 2009 American black comedy crime drama film directed by Werner Herzog and starring Nicolas Cage, Eva Mendes, Tom Bower, Jennifer Coolidge, Alvin 'Xzibit' Joiner, Val Kilmer, and Brad Dourif. Though the film's title and story loosely resemble that of Abel Ferrara's 1992 film Bad Lieutenant, according to Herzog, it is neither a sequel nor a remake; its only commonality is a corrupt policeman as the central character. Nonetheless, the director of the original Bad Lieutenant film, Abel Ferrara, expressed dismay that the Herzog film was being made. Both Bad Lieutenant films were produced by Edward R. Pressman.

The film premiered on September 9, 2009 at the 66th Venice International Film Festival where it won the Christopher D. Smithers Foundation Special Award for Herzog. It opened in general release in the United States on November 20, 2009.
