Örvar-Oddr (Old Norse Ǫrvar-Oddr, "Arrow-Odd" or "Arrow's Point") is a legendary hero about whom an anonymous Icelander wrote a fornaldarsaga in the latter part of the 13th century. Örvar-Odds saga, the Saga of Örvar-Odd, became very popular and contains old legends and songs. He also appears in Hervarar saga and, concerning the battle on Samsø, in Gesta Danorum.
Oddr was the son of Grim Lodinkinni and the grandson of Ketil Höing (both of whom have their own sagas) of Hålogaland. When he was an infant, a völva predicted that he would be killed by his own horse Faxi, at the place where he was born, at the age of 300.
In order to undo the prediction, he killed his horse, buried it deep in the ground and left his home intending never to return again. As he was leaving, his father gave him some magic arrows (Gusisnautar) which soon earned him the cognomen arrow. After a voyage to Finnmark, Bjarmaland and Jotunheim, he fought successfully against several Vikings.
However, when he encountered the Swedish champion Hjalmar, he met his match. The fight was even and the two warriors not only became friends, but entered sworn brotherhood.
The two heroes fought many battles together (for more see Hjalmar), until after the famous battle of Samsø against the sons of Arngrim, Örvar-Oddr had to bring the dead Hjalmar (killed by Angantyr) to Uppsala and his betrothed Ingeborg, the daughter of the Swedish king.
