Baldr (also Balder, Baldur) is a god in Norse mythology.
In the 12th century, Danish accounts by Saxo Grammaticus and other Danish Latin chroniclers recorded a euhemerized account of his story. Compiled in Iceland in the 13th century, but based on much older Old Norse poetry, the Poetic Edda and the Prose Edda contain numerous references to the death of Baldr as both a great tragedy to the Æsir and a harbinger of Ragnarök.
According to Gylfaginning, a book of Snorri Sturluson's Prose Edda, Baldr's wife is Nanna and their son is Forseti. In Gylfaginning, Snorri relates that Baldr had the greatest ship ever built, named Hringhorni, and that there is no place more beautiful than his hall, Breidablik.
