The Gododdin (Welsh pronunciation: [ɡɔˈdɔðɪn]) were a 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 memorialises the Battle of Catraeth and is attributed to Aneirin.

Cunedda, legendary founder of the Kingdom of Gwynedd in north Wales, is supposed to have been a Manaw Gododdin warlord who migrated southwest during the 5th century.

In around 600 the Gododdin raised a force of about 300 men to assault the Angle stronghold of Catraeth, perhaps Catterick, North Yorkshire.

[8] Shortly afterwards this came under a unified England, then in 1018 Malcolm II brought the region as far as the River Tweed under Scottish rule.
