Harold Harefoot, also Harold I, (c. 1015–March 17, 1040) was King of England from 1035 to 1040. He was said to be the son of Canute the Great, King of England, of Denmark, of Norway, some of Sweden, by his handfast wife Aelgifu of Northampton, although there was some skepticism that he was Canute's son. He earned the name "Harefoot" for his speed, and the skill of his huntsmanship.
