Böðvildr, Beadohild, Bodil or Badhild was a princess, the daughter of the evil king Níðuðr/Niðhad/Niðung who appears in Germanic legends, such as Deor, Völundarkviða and Þiðrekssaga. Initially, she appears to have been a tragic victim of Wayland the smith's revenge on her father, but in later Scandinavian versions, she becomes Wayland's wife and the mother of the hero Viðga of the Þiðrekssaga and medieval Scandinavian ballads.

King Niðhad, Níðuðr, Niðungr or Niduth was a cruel king in Germanic legend. He appears as Níðuðr in the Old Norse Völundarkviða, as Niðung in the Þiðrekssaga, and as Niðhad in the Anglo-Saxon poems Deor and Waldere.
