Helluland (Old Norse pronunciation: [ˈhelːoˌlɑnd]) is one of the three lands, the others being Vinland and Markland, seen by Bjarni Herjólfsson, encountered by Leif Erikson and further explored by Thorfinn Karlsefni Thórdarson around AD 1000 on the North Atlantic coast of North America. As some writers refer to all land beyond Greenland as Vinland, Helluland is sometimes considered a part of Vinland.
