Hermóðr the Brave (Old Norse "war-spirit", anglicized as Hermod) is a figure in Norse mythology, the son of god Odin.

Hermóðr appears distinctly in section 49 of the Prose Edda book Gylfaginning. There, it is described that the gods were speechless and devastated at the death of Baldr, unable to react due to their grief. After the gods gathered their wits from the immense shock and grief of Baldr's death, Frigg asked the Æsir who amongst them wished "to gain all of her love and favor" by riding the road to Hel. Whoever agreed was to offer Hel a ransom in exchange for Baldr's return to Asgard. Hermóðr agrees to this and set off with Sleipnir to Hel.

Hermóðr rode Odin's horse Sleipnir for nine nights through deep and dark valleys to the Gjöll bridge covered with shining gold, the bridge being guarded by the maiden Móðguðr 'Battle-frenzy' or 'Battle-tired'. Móðguðr told Hermóðr that Baldr had already crossed the bridge and that Hermóðr should ride downwards and northwards.

Upon coming to Hel's gate, Hermóðr dismounted, tightened Sleipnir's girth, mounted again, and spurred Sleipnir so that Sleipnir leapt entirely over the gate. So at last Hermóðr came to Hel's hall and saw Baldr seated in the most honorable seat. Hermóðr begged Hel to release Baldr, citing the great weeping for Baldr among the Æsir. Thereupon Hel announced that Baldr would only be released if all things, dead and alive, wept for him.
