Hervör is the name shared by two female characters in the Tyrfing Cycle, presented in The Saga of Hervör and Heidrek with parts found in the Poetic Edda. The first, the Viking Hervör, challenged her father Angantýr's ghost in his gravemound for his cursed sword Tyrfing. She had a son, Heidrek, father of the other Hervör. The second Hervör was a commander killed in battle with her brother.
