Markland is the name given to one of three lands on North America's North Atlantic shore discovered by Leif Eriksson around AD 1000. It was located south of Helluland and north of Vinland and almost certainly was part of the Labrador coast in Canada, as Labrador lies in the heavily forested taiga region of the Northern Hemisphere north of the location of Vinland on the island of Newfoundland.

Although it was never apparently settled by Norsemen, there were probably a number of later expeditions from Greenland to gather timber.

The Saga of the Greenlanders tells that Leif Eriksson set out in the year 1002 or 1003 to follow the route first described by Bjarni Herjólfsson. The first land Eriksson went to was covered with flat rocks (Old Norse: hella). He therefore called it Helluland meaning "Land of the Flat Stones". Next Eriksson came to a land that was flat and wooded, with white sandy beaches, which he called this Markland ("Forest Land"). Ericson's crew cut down trees and took them to Greenland, because Greenland possesses only one small forest and normally relies on driftwood or imports for lumber. The Saga of the Greenlanders also tells of 160 men and women who settled in Markland for winter protection led by Thorfinn Karlsefni (Þorfinnr Karlsefni Þórðarson), c. 1010.
