Robert de Brus, 5th Lord of Annandale

Robert de Brus, fifth Lord of Annandale, called the Competitor (c. 1215–1295), was a Scottish magnate and regent during Alexander III's minority. A great-great-grandson of David I, he claimed the crown after the Maid of Norway died in 1290, but Edward I awarded the throne to his rival John Balliol in 1292.

Robert then resigned Annandale and his claim to his eldest son. He died at Lochmaben in 1295 and was buried at Gisborough Priory, his grandson becoming King Robert I.
