Lokrur is an Icelandic mythological rímur cycle dated to ca. 1400. It narrates the journey of the god Thor to Útgarða-Loki, a myth also preserved in Snorri Sturluson's 13th century Prose Edda part Gylfaginning. Compared with the version in Gylfaginning, the Lokrur version is often more detailed, with fleshed-out descriptions where Gylfaginning has an understated and terse text. The cycle consists of four rímur, the first in stafhent and the rest in ferskeytt meter. The rímur are only preserved in one medieval manuscript, Staðarhólsbók.
