Wither (Swedish: Vittra) is a Swedish 2012 horror film directed by Sonny Laguna and Tommy Wiklund, who wrote and produced the film along with David Liljeblad. It is based on the 1981 horror film The Evil Dead by Sam Raimi. The plot follows a group of young Swedes who travel to an abandoned cabin over the weekend. The cabin turns out to be the home of a Vittra, and the friends have to fight for their lives, aided by the hunter Gunnar (Johannes Brost).

The film was marketed as the first Swedish zombie film shown in cinemas and was incorrectly stated by several Swedish newspapers as being the first Swedish zombie film. The first Swedish zombie film is Terror i Rock 'n' Roll Önsjön from 2001.
