In Norse mythology, Váli is a son of the god Odin and the giantess Rindr. Váli has numerous brothers including Thor, Baldr and Víðarr. He was birthed for the sole purpose of killing Höðr as revenge for Höðr's accidental murder of his half-brother, Baldr. He grew to full adulthood within one day of his birth, and slew Höðr. Váli is fated to survive Ragnarök.
The Váli myth is referred to in Baldrs draumar:
And in Völuspá:
The Prose Edda also mentions him. Gylfaginning contains this passage:
"One is called Ali or Váli, son of Odin and Rindr: he is daring in fights, and a most fortunate marksman."
The same text also states that he will survive Ragnarök, along with his brother Víðarr and the sons of Thor, Móði and Magni.
There is another figure in Norse mythology named Váli, a son of Loki by Sigyn, who was transformed by the gods into a slavering wolf who tore out the throat of his brother Narfi to punish Loki for his crimes. See Váli (son of Loki).
In Gesta Danorum the figure Bous corresponds to Váli.
