Olaf Gudrødsson, or as he was named after his death Olaf Geirstad-Alf, was a legendary Norwegian king of the House of Yngling from the Ynglinga saga. He was the son of Gudrød the Hunter and the brother of Halfdan the Black. Gudrød and Olaf conquered a large part of Raumarike.
Gudrød died when Olaf was twenty years old and he and Halfdan divided their kingdom between them. Olaf took the southern part and resided in Geirstad. They only inherited Vestfold because Alfgeir took Vingulmark for himself and made his son Gandalf Alfgeirsson its king.
The Ynglinga saga relates that Olaf was a skillful man and a great warrior. He was also handsome, big and strong. He was the father of Ragnvald the Mountain-High.
During the reigns of Olaf and Halfdan the Black, Värmland started to pay tribute to the Swedish king Erik Anundsson instead.
He died of illness. Tjodolf of Hvin sang about him:
After his death, he was worshipped as an elf, and was called the Geirstad-alf (the "elf of Geirstad").
A hypothesis identifies Geirstad with Gjerstad near Gokstad, and his burial with the Gokstad Ship.
