Archibald Douglas, 4th Earl of Douglas, Duke of Touraine, was a Scottish nobleman and warlord. He is sometimes given the epithet "Tyneman", but this may be a reference to his great-uncle Sir Archibald Douglas.

Archibald Douglas, Earl of Douglas and Wigtown, Lord of Galloway, Douglas and Bothwell, called Archibald the Grim or Black Archibald, was a late medieval Scottish nobleman. Archibald was the bastard son of Sir James "the Black" Douglas, Robert I's trusted lieutenant, and an unknown mother. A first cousin of William 1st Earl of Douglas, he inherited the earldom of Douglas and its entailed estates as the third earl following the death without legitimate issue of James 2nd Earl of Douglas at the Battle of Otterburn.
