Aslaug, also called Aslög, Kráka or Kraba, is a figure in Norse mythology who appears in Snorri's Edda, the Völsunga saga and in the saga of Ragnar Lodbrok as one of his wives.

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.
