In Norse mythology, which realm is Valhalla located in?

In Norse mythology, Valhalla is located in Asgard.

Asgard is the realm associated with the gods known as the Æsir. Valhalla is described as Odin’s great hall there, where warriors who die in battle may be received after being selected by supernatural battle figures. Its placement in Asgard distinguishes it from Hel, the broader realm associated with many of the dead, and from Fólkvangr, Freyja’s destination for part of those slain in combat.

Norse mythology survives through sources written down in medieval Iceland, especially the Poetic Edda and Prose Edda. These texts sometimes present overlapping or differently emphasized traditions, but Valhalla’s connection with Odin and Asgard is consistent in the best-known accounts. Asgard itself is often pictured as one of the mythological worlds linked by Yggdrasil, the cosmic tree, rather than as an ordinary human location.
