The Gododdin were a P-Celtic speaking Brittonic people of north-eastern Britannia, the area known as the Hen Ogledd or Old North (modern south-east Scotland and north-east England), in the sub-Roman period. Descendants of the Votadini, they are best known as the subject of the 6th-century Welsh poem Y Gododdin, which memorializes the Battle of Catraeth and is attributed to Aneirin.
