Njörðr (Old Norse: Njörðr) is a deity of the Vanir associated with the sea, coastal waters, wind, fishing, and seafaring prosperity. He is the father of Freyr and Freyja and came to dwell among the Æsir as a hostage following the Æsir-Vanir War. He rules from his coastal hall Nóatún (Ship-Enclosure), named in Grímnismál. Lokasenna (st. 34) references his governance of winds and of those who go to sea, and Ynglinga saga credits him with abundant fishing and prosperity.

Njörðr’s most narratively developed episode is his incompatible marriage to the hunting goddess Skaði, recounted in Gylfaginning. Skaði came to Ásgarðr seeking compensation for her father Þjazi’s death and was offered a husband chosen by feet alone from behind a curtain. She chose Njörðr, believing she was selecting Baldr. Their marriage failed because each could not endure the other’s home: Skaði could not bear the coastal hall Nóatún, while Njörðr could not bear her mountain home Þrymheimr. Each spent nine nights in the other’s home before separating.

Ynglinga saga also preserves a tradition that Njörðr became a legendary king of Sweden and received blót sacrifices after his death.
