North America is the part of the "New World." The third-largest continent extends from the tiny Aleutian Islands in the northwest to the Isthmus of Panama in the south. If I go by the history, North America and South America were named after Italian navigator Amerigo Vespucci. He was the first European to identify it as an entirely separate landmass, not part of the East Indies.

Today, North America is home to the citizens of Canada, the United States, Greenland, Mexico, Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and the island countries and territories of the Caribbean Sea and western North Atlantic Ocean.
