In Norse Mythology, Bragi is the God of poetry, (adopted?) son of Odin and the giantess Gunlod. He was the chief poet of Odin and said to be very wise. He was married to Idun and he had runes cut on his tounge.
In The Lay of Hakon, Bragi is in Valhalla with Odin who tells Bragi to go out and greet Hakon as he arrives. Bragi is also in Valhalla alongside Odin in The Lay of Eirik, and Odin refers to Bragi as one who "knowest everything well". During the feast in Asgard attended by Aegir, it is Bragi who relates to Aegir the tales of the gods.

There was a ninth century skald named Bragi Boddason and some believe he may have been raised to a god by later writers. Others believe Bragi was an aspect of Odin.
