North America and surrounding islands

  • Northernmost point — Kaffeklubben Island, Greenland 83°40′N 29°50′W / 83.667°N 29.833°W. Although politically part of the Kingdom of Denmark, Greenland is geologically part of the North American Plate. If non-permanent islands are included, then the northernmost point is Qeqertaq Avannarleq. If Greenland is excluded from North America, the northernmost point is Cape Columbia, Ellesmere Island, Nunavut, Canada 83°8′N 74°13′W / 83.133°N 74.217°W.
  • Southernmost point — Cocos Island, Costa Rica 5°31′8″N 87°4′18″W / 5.51889°N 87.07167°W
  • Westernmost point — The westernmost point depends on the definition of "westernmost". If following the International Date Line, it would be Cape Wrangell on Attu Island, Alaska, United States 52°55′28″N 172°28′22″E / 52.92444°N 172.47278°E, or the tiny (ca. 200m diameter) Peaked Island, just off the coast to the west. However, if the border between east and west is defined by the 180th meridian, the westernmost point is the West Point of Amatignak Island 51°17′N 179°9′W / 51.283°N 179.150°W, as Attu Island is in the Eastern Hemisphere.
  • Easternmost point — Nordostrundingen, Greenland 81°26′25″N 11°29′22″W / 81.44028°N 11.48944°W. If Greenland is excluded, then the easternmost point is Cape Spear, Newfoundland, Canada 47°31′25″N 52°37′10″W / 47.52361°N 52.61944°W. Again, if one uses the technical definition of longitude, it is Pochnoi Point on Semisopochnoi Island, Alaska, 51°57′N 179°52′E / 51.950°N 179.867°E since the state stretches into the Eastern Hemisphere. However, other sources argue it would be Cape Wrangell on Attu Island, Alaska, United States at 52°55′28″N 172°28′22″E / 52.92444°N 172.47278°E, as well as the tiny (ca. 200m diameter) Peaked Island, just off the coast to the west.
