Auðr the Deep-Minded (Old Norse: Auðr in djúpúðga) was a legendary Norse princess, the daughter of Ivar Vidfamne, and the mother of Harald Wartooth, who appears in Sögubrot, Hversu Noregr byggdist and in the Lay of Hyndla.
Ivar Vidfamne took advantage of the situation by telling Hrœrekr that Auðr was unfaithful with Helgi.
The ruse was successful and Hrærekr slew his brother Helgi, after which it was easy for Ivar to attack Hrœrekr and to kill him as well.
One night, as they were harboured in the Gulf of Finland, he had a strange dream, and he asked his foster-father Hörð what it meant.
As the throne of Sweden and Denmark was vacant, Auðr's son Harald Wartooth departed to Scania to claim his inheritance, with the help of his stepfather Ráðbarðr.
