John Drummond (1714–1747), titular 7th Earl and 4th Duke of Perth, often referred to by his courtesy title Lord John Drummond, was a Franco-Scottish nobleman, soldier and Jacobite. Drummond served as an officer in the French Army, but is perhaps best known for his participation in the Jacobite rising of 1745, during which he was one of the senior Jacobite staff officers in addition to leading the Jacobite Royal Scots, a regiment raised by him in France.
