Sigrid the Haughty (Old Norse:Sigríðr (hin) stórráða), also known as Sigrid Storråda (Swedish), is a Scandinavian queen appearing in Norse sagas. Sigrid is named in several late and sometimes contradictory Icelandic sagas composed generations after the events the stories describe, but there is no reliable, historical evidence attesting to the veracity of her depiction in those tales. She is reported by Heimskringla to have been the wife of Eric the Victorious of Sweden, as being sought after by Olaf Tryggvasson, and then married to Sweyn Forkbeard of Denmark.
