Margaret Douglas, Countess of Douglas (died c. 1474), known as the Fair Maid of Galloway, was a Scottish noblewoman, and a member of the Black Douglas family towards the end of the family's position as a major power in Scotland. She was the daughter of Archibald Douglas, 5th Earl of Douglas, and Eupheme Graham, daughter of Patrick Graham, Earl of Strathearn and Euphemia Stewart, Countess of Strathearn. She acquired Galloway when her two brothers (one of whom was William Douglas, 6th Earl of Douglas) were murdered at the Black Dinner in Edinburgh Castle.
