Arthur, malédiction (transl. Arthur, curse) is a 2022 French meta psychological horror film directed by Barthélemy Grossmann. It is the fourth installment overall in the Arthur film series, which is based on the eponymous children's fantasy novel series by Luc Besson, and serves a spin-off in which the original trilogy is presented as a film-within-a-film. The film stars an ensemble cast, and follows a group of Arthur fans who discover the house that was used as one of the trilogy live-action sequences set, only to find themselves being hunted down one-by-one by a group of deranged role-players.

Production secretly started in 2020 in Normandy. It is the first Arthur film to be rated "prohibited to spectators under 12 years old" by the French Cinematographic Works Classification Board and the first to be filmed in French language. It is also the only film in the series not distributed by EuropaCorp following the company financial difficulty.

Arthur, malédiction was released in France on 29 June 2022 by Apollo Films and EuropaCorp Distribution. It was poorly received by critics, and grossed only €1 million against a €2 million budget, making it a box-office bomb.
