Gurguit Barbtruc (Welsh: Gwrgant Farfdrwch) was a legendary king of the Britons as accounted by Geoffrey of Monmouth. He was the son of Belinus and was said to have found a home for the Irish people.
Gurguit was a peaceful king who followed in the manner of his father and grandfather. Yet, when the king of the Danes refused to pay tribute to Belinus's son, Gurguit took a fleet and invaded Denmark, killing the king and reducing the country to subservience.
