Arthur and the Revenge of Maltazard (French: Arthur et la Vengeance de Maltazard) is a 2009 English-language French live-action/animated fantasy film directed and co-written by Luc Besson, based on the third book of the Arthur children's books series by Besson. It is the sequel to Arthur and the Minimoys (2006), and the second installment in the Arthur film series.

Arthur and the Revenge of Maltazard was released theatrically in France on 2 December 2009 by EuropaCorp. The film received mixed reviews from critics in France and was received negatively outside France. Like its predecessor, it was a box-office success in France but was a box-office bomb internationally. It was released direct-to-video in the United States by 20th Century Fox Home Entertainment, while in the United Kingdom and Ireland, it was edited as one film with the third film under the title Arthur and the Great Adventure. As a result, the film generated huge losses for EuropaCorp.

A sequel, titled Arthur 3: The War of the Two Worlds and shot back-to-back, was released in 2010 in France.
