Helluland is the name given to 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.

Vinland, Vineland, or Winland was an area of coastal North America explored by Vikings. Leif Eriksson landed there around 1000 AD, nearly five centuries before the voyages of Christopher Columbus and John Cabot. The name appears in the Vinland Sagas, and describes Newfoundland and the Gulf of Saint Lawrence as far as northeastern New Brunswick. Much of the geographical content of the sagas corresponds to present-day knowledge of transatlantic travel and North America.
