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.

A legendary saga or fornaldarsaga is a Norse saga that, unlike the Icelanders' sagas, takes place before the settlement of Iceland. There are some exceptions, such as Yngvars saga víðförla, which takes place in the 11th century. The sagas were probably all written in Iceland, from about the middle of the 13th century to about 1400, although it is possible that some may be of a later date, such as Hrólfs saga kraka.
