Charles Spencer (1706-1758), Third Duke of Marlborough, known as The Earl of Sunderland between 1729 and 1733, was the son of Charles Spencer, 3rd Earl of Sunderland and Lady Anne Churchill.

Spencer was a politician and General in the British Army, where he fought alongside King George II at the Battle of Dettingen in 1745. He briefly served as Lord Privy Seal in 1755. He is best known for his service as Commander-in-Chief of the British Forces in the early part of the Seven Years’ War (1754-1763) where he led British forces during the Raid on St Malo in 1758. He died in Germany shortly thereafter.

Charles Spencer, Duke of Marlborough, is a distant ancestor of Diana, Princess of Wales, the first wife of Charles, Prince of Wales.
