Halfdan the Valiant (Hálfdan snjalli) (7th century?) was a legendary Scanian prince, who was the father of Ivar Vidfamne according to Hervarar saga, the Ynglinga saga, Njal's Saga and Hversu Noregr byggdist.[1] The genealogical work Hversu Noregr byggdist gives his father as Harald the Old, his grandfather as Valdar and his great-grandfather as Hróarr (i.e. the Hroðgar of Beowulf).[2]
