John Cabot (Italian: Giovanni Caboto; c. 1450 – c. 1499) was an Italian navigator and explorer whose 1497 discovery of parts of North America under the commission of Henry VII of England is commonly held to have been the first European encounter with the mainland of North America since the Norse Vikings visits to Vinland in the eleventh century. The official position of the Canadian and British governments is that he landed on the island of Newfoundland.
