Sir Henry Percy KG (20 May 1364 – 21 July 1403), commonly known as Sir Harry Hotspur, or simply Hotspur, was a late mediaeval English nobleman. He was known as one of the most valiant knights of his day, and was a significant captain during the Anglo-Scottish wars. He later led successive rebellions against Henry IV of England, and was slain at the Battle of Shrewsbury in 1403 at the height of his career.
