In Norse mythology, Angrboða is the mother of the wolf Fenrir, an enemy at Ragnarök.
Angrboða is a giantess associated with Jötunheimr and is described in the Poetic Edda and Prose Edda as Loki’s partner. Their children include Fenrir, the world serpent Jörmungandr, and Hel, ruler of the realm of the dead. These offspring are closely connected with the disasters foretold for the gods.
The gods become alarmed by the children’s dangerous destinies. Jörmungandr is cast into the sea surrounding Midgard, Hel is sent to govern the dead, and Fenrir is eventually bound by Gleipnir. At Ragnarök, all three play roles in the destruction of the old cosmic order.
Angrboða is sometimes confused with Sigyn, Loki’s wife in another myth. Sigyn is associated with Loki’s punishment, while Angrboða is the giantess who bears Loki’s three monstrous children.
