Helgi Hundingsbane is a hero in Norse sagas. Helgi appears in Volsunga saga and in two lays in the Poetic Edda named Helgakviða Hundingsbana I and Helgakviða Hundingsbana II. The Poetic Edda relates that Helgi and his mistress Sigrún were Helgi Hjörvarðsson and Sváva of the Helgakviða Hjörvarðssonar reborn. They were once again reborn as Helgi Haddingjaskati and Kára whose story survives as a part of the Hrómundar saga Gripssonar.

The Völsunga saga is a legendary saga, a late 13th-century prose rendition in Old Norse of the origin and decline of the Völsung clan. It is one of the most famous legendary sagas and an example of a "heroic saga" that deals with Germanic heroic legend.
