The Flugumýrarbrenna () was a quickfire (arson) that took place 22 October 1253 in Iceland during the Age of the Sturlungs. The powerful Icelandic goði chieftain Gissur Þorvaldsson had returned from Norway with the Norwegian King's favour, and had settled in Flugumýri, an old homestead in Blönduhlíð in Skagafjörður where the chieftains of the Ásbirningar held their seat. The Flugumýri Arson lived for a long time in folk tales, and some scholars believe that it was inspired by the arson in Njáls saga (or vice versa).[citation needed]
