Yngvars saga víðförla is a legendary saga said to have been written in the twelfth century by Oddr Snorrason. The tale tells of a Viking expedition to somewhere in southern Russia, probably the present day region of Georgia in the Caucasus.

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.
