In Norse mythology, Útgarða-Loki is the ruler of the castle Útgarðr in Jötunheimr. He is one of the jötnar and his name means literally "Loki of the Outyards" or "Loki of the Outlands", to distinguish him from Loki, the companion of Thor. He was also known as Skrýmir or Skrymir.

The terms Jötunheimr or Jötunheimar refer to either a land or multiple lands respectively in Nordic mythology inhabited by the jötnar. Jötunheimar are typically, but not exclusively, presented in Eddic sources as prosperous lands located to the north and are commonly separated from the lands inhabited by gods and humans by barriers that cannot be traversed by usual means.
