Erik Refilsson was a legendary king of Sweden of the House of Munsö, who lived in the late 9th century.
One of the few surviving Scandinavian sources that deal with Swedish kings from this time is Hervarar saga.
It says: Then Eric the son of Refil succeeded to the Kingdom.
The sons of Eric Björnsson were Önund of Upsala and King Björn.
Then the Swedish Realm again came to be divided between brothers.
