Arons saga Hjörleifssonar (standardised Old Norse spelling: Arons saga Hjǫrleifssonar) recounts the life of Aron Hjörleifsson (c. 1200–55), an important contemporary of Sturla Sighvatsson and Bishop Guðmundr Arason.
The saga has been dated to around 1340, though it survives first in a fifteenth-century vellum fragment (AM 551d beta 4to), with the earliest complete texts being the paper manuscripts AM 212 fol., AM 426 fol., and AM 399 4to (known as the Codex Resenianus).
It seems to have been written in the wake of the attempts to have Guðmundr canonised around 1320.
It claims that Aron was one of the most famous warriors of his time, becoming an outlaw at the hands of Sturla Sighvatsson, travelling as a pilgrim to Jerusalem, and ending his life at the court of Haakon IV of Norway.
