Archibald Douglas, 6th Earl of Angus (c. 148922 January 1557) was a Scottish nobleman active during the reigns of James V and Mary, Queen of Scots. He was the son of George, Master of Angus, who was killed at the Battle of Flodden, and succeeded as Earl of Angus on the death of his grandfather, Archibald. Through his daughter, Margaret, he was the grandfather of Henry Stuart, Lord Darnley and therefore the great-grandfather of James VI and I.

Angus had a daughter named Lady Janet Douglas with Lady Jane of Traquair and seized some property belonging to his then wife, Margaret Tudor, an estate at Newark and proceeded to live in it openly with his wife and illegitimate child. Margaret, however, was more annoyed with Douglas over his seizure and usage of her dower income as dowager queen of Scotland than the birth of his illegitimate daughter. Margaret avenged his neglect by refusing to support his claims for power and by secretly trying through Albany to get a divorce. In Edinburgh, Angus held his own against the attempts of the Earl of Arran, to dislodge him. But the return of Albany in 1521, with whom Margaret now sided against her husband, deprived him of power. The regent took the government into his own hands, Angus was charged with high
