Holuhraun is a large lava field just north of the Vatnajökull ice cap, in the Icelandic Highlands, in Suður-Þingeyjarsýsla, Northeastern Region, Iceland. The lava field was created by fissure eruptions. 

Holuhraun is the site of an ongoing volcanic eruption starting on August 29, 2014, and has now produced  the largest lavafield in Iceland since 1783. The new lavafield has been called Nornahraun, or Witches Lavafields, due to an abundance of wind spun thread like lava extrusions known as Pele’s hair which in Icelandic are known as Nornahár or Witches hair.
