Rivallo (Welsh: Rhiwallon) was a legendary king of the Britons as told by Geoffrey of Monmouth. He was the son of King Cunedagius.

During the time he ruled he was troubled by disasters: a rain of blood which lasted three days, a terrible plague, and a great swarm of flies. After he died his son Gurgustius became king.
