Brutus Greenshield (Welsh: Bryttys darian las) was a legendary king of the Britons as accounted by Geoffrey of Monmouth. He was the son of King Ebraucus.

Brutus II, surnamed Greenshield, was the eldest of twenty sons and the only remaining son of Ebraucus in Britain at the time of his death. All Ebraucus's other sons were in Germany establishing a new kingdom there. He reigned for twelve years after his father's death and was succeeded by his son, Leil.
