Henry Percy, 1st Earl of Northumberland, 4th Baron Percy, titular King of Mann, KG, Lord Marshal (10 November 1341 – 20 February 1408) was the son of Henry de Percy, 3rd Baron Percy, and a descendant of Henry III of England. His mother was Mary of Lancaster, daughter of Henry, 3rd Earl of Lancaster, son of Edmund, Earl of Leicester and Lancaster, who was the son of Henry III.

Henry Percy was originally a follower of Edward III of England, for whom he held high offices in the administration of northern England. At a young age he was made Warden of the Marches towards Scotland in 1362, with the authority to negotiate with the Scottish government. In February 1367 he was entrusted with the supervision of all castles and fortified places in the Scottish marches. He went on to support King Richard II and was created an Earl and briefly given the title of Marshal of England. After Richard elevated his rival Ralph Neville to the position of Earl of Westmorland in 1397, Percy supported the rebellion of Henry Bolingbroke, who became King as Henry IV.

On King Henry IV's coronation he was appointed Constable of England and granted the lordship of the Isle of Man. Percy and his son, Henry Percy, known as "Hotspur", were given the task of subduing the rebellion of Owain Glyndŵr, but their attempts to make peace with the Welsh rebels did not meet with the king's approval.
