In Norse mythology, Útgarða-Loki (Anglicized as Utgarda-Loki, Utgard-Loki, and Utgardsloki) 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. He was also known as Skrýmir or Skrymir.

==Prose Edda== In the Prose Edda book Gylfaginning (chapter 44), the enthroned figure of Third reluctantly relates a tale in which Thor, Loki and Thor's servants, Þjálfi and Röskva are traveling to the east. They arrive at a vast forest in Jötunheimr, and they continue through the woods until dark. The four seek shelter for the night and discover an immense building. Finding shelter in a side room, they experience earthquakes through the night. The earthquakes cause all four to be fearful, except Thor, who grips his hammer in defense. The building turns out to be the huge glove of Skrýmir, who has been snoring throughout the night, causing what seemed to be earthquakes. The next night, all four sleep beneath an oak tree near Skrýmir in fear.
