Gurgustius (Welsh: Gwrwst) was a legendary king of the Britons as accounted by Geoffrey of Monmouth. He came to power in 788BC.
He was the son of King Rivallo and was succeeded by his own son Sisillius I, and then Jago, who was Gurgustius' nephew (or possibly his grandson). Geoffrey has nothing to say of him beyond this.
