Harald Harefoot (c. 1015 – March 17, 1040) was King of England from 1035 to 1040. His cognomen "Harefoot" was for his fleetness of foot and his skill as a huntsman. He was the son of Canute the Great, King of England, Denmark, Norway, and some of the Kingdom of Sweden, through his handfast wife Aelgifu of Northampton. In some quarters there were doubts that he was a true son of Knutr, although his supporters claimed this was mere rumor-mongering by his enemies. Harold had a son, Elfwine, who departed for the mainland to become a monk in later years.
