Henry Percy, 4th Earl of Northumberland, KG (c. 1449 – 28 April 1489) was an English aristocrat during the Wars of the Roses. After losing his title when his father was killed fighting the Yorkists, he later regained his position. He led a major portion of Richard III's army at the Battle of Bosworth, but failed to commit his troops. He was briefly imprisoned by Henry VII, but later restored to his position. A few years later he was murdered by citizens of York during an anti-tax riot.
