Gautreks saga (Gautrek's Saga) is a Scandinavian legendary saga put to text towards the end of the 13th century which survives only in much later manuscripts. It seems to have been intended as a compilation of traditional stories, often humorous, about a legendary King Gautrek of West Geatland, to serve as a kind of prequel to the already existing Hrólfs saga Gautrekssonar (Saga of Hrólf son of Gautrek). See also king of the Geats.
