Robert de Bruce (Robert VI Bruce) (c. 1253 - 1304), 6th Lord of Annandale, Earl of Carrick in right of his wife, was a Scottish lord.
He was the son and heir of Robert Bruce the Competitor († 1295), who from 1290 claimed succession to the throne of Scotland, being one of the two main claimants to the throne.
He supported his father who disputed the throne with John Balliol after the death of Alexander III of Scotland (1286). He allied himself with the King of England Edward I, to triumph over his rival, but he was deceived by the English monarch who, after the victory refused to give him the throne.
He then united with William Wallace to deliver Scotland, but he abandoned him out of jealousy, and allied himself again with the English. However he returned to the national cause after Wallace's defeat at Falkrirk in 1298.
