Maelström is a 2000 Canadian absurdist psychological drama film written and directed by Denis Villeneuve. It stars Marie-Josée Croze as a depressed young businesswoman who becomes romantically involved with the son of a man she killed in a hit-and-run accident. Employing fantasy and comedic elements, Maelström is narrated by a talking fish.

Villeneuve conceived of the story, basing it on his interest in car accidents and modelling the protagonist after various women he knew. He cast Croze, then a novice actress, in the lead role. Filming took place in Montreal in 1999, with animatronics to depict the fish narrator.

The film premiered at the Montréal World Film Festival in August 2000 and received positive reviews, with some detractors. It won five Genie Awards, including Best Motion Picture, and the FIPRESCI Prize at the 51st Berlin International Film Festival. Maelström was announced as Canada's submission for the Academy Award for Best International Feature Film at the 73rd Academy Awards, but it was not nominated.
