A vittra (plural: vittror) is a type of wight (a term for supernatural spirits) from northern Sweden. They were associated with herding, either cattle or reindeer; they were believed to live normally among humans and only revealed a supernatural nature if their livestock were mistreated. Like the hulder and the skogsrå, the vittra is also associated with longing and desire. The vittra appears as a beautiful, female wight who seduces men in the forest.

Vittror are central to the storyline of season 1, episode 4 of Hilda.

The Swedish film Vittra, or its American title Wither, has a Vittra as the main villain.
