Nanna is a goddess in Norse mythology. She belongs to the race of the Aesir. In Snorri Sturluson's Edda, Nanna is the daughter of Nepr, who is named in the Þulur as the son of Odin, she is the wife of Baldr and through him mother of Forseti.

In the Icelandic sources of Snorri Sturluson, after the death of her husband Baldr, Nanna, broken-hearted, collapses dead at his funeral ceremonies and is cremated with him. So Hermod, a son of Odin, who has the mission to free Baldr from the world of the dead, meets him together with Nanna and he receives from Baldr the ring Draupnir for Odin and from Nanna a headscarf for Frigg and a golden finger ring for Fulla.


The Danish historian Saxo Grammaticus states that Nanna is the daughter of the Norwegian king Gevarus, who is courted by Balderus and the Swedish king's son Hötherus. Choosing Hötherus because, in her opinion, marriages between humans and gods are unhappy, Balderus challenges Hötherus to a fight. This leads to war between gods and men, in which the gods are defeated, and Balderus is killed by Hötherus through special circumstances.

In the Liederedda another Nanna is known, who is the daughter of a certain Nökkvi.
