Greenland

Greenland is, by area, the world's largest island that is not a continent. With a population of 56,452 (January, 2010 estimate) it is the least densely populated dependency or country in the world.
The name Greenland comes from the early Scandinavian settlers. In the Icelandic sagas, it is said that Norwegian-born Erik the Red was exiled from Iceland for murder. He, along with his extended family and thralls, set out in ships to find a land rumoured to lie to the northwest. After settling there, he named the land Grœnland ("Greenland"), supposedly in the hope that the pleasant name would attract settlers.
Greenland was also called Gruntland ("Ground-land") and Engronelant (or Engroneland) on early maps. Whether green is an erroneous transcription of grunt ("ground"), which refers to shallow bays, or vice versa, is not known. The southern portion of Greenland (not covered by glaciers) is green in the summer.
