Nordic noir, also known as Scandinavian noir or Scandi noir, is a genre of crime fiction usually written from a police point of view and set in Scandinavia or Nordic countries.

It contrasts with the whodunit style such as the English country house murder mystery. The popularity of Nordic noir has extended to the screen, such as The Killing, The Bridge, Trapped, and Bordertown.
