Hrólfs saga kraka, the Saga of King Rolf Kraki, is a late legendary saga on the adventures Hrólfr Kraki, a semi-legendary king in what is now Denmark, and his clan, the Skjöldungs. The events can be dated to the late 5th century and the 6th century. A precursor text may have dated to the 13th century, but the saga in the form that survived to this day dates to c. 1400. Forty-four manuscripts survive, but the oldest one of them is from the 17th century, although a manuscript is known to have existed c. 1461 at the monastery of Möðruvellir in Iceland.

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.
