The role of discoverer of the Americas is variously attributed to the following people, depending on context and definition:

• Native Americans, the first people to live in America (see Paleo-Indians, Clovis Culture, Models of migration to the New World, Pre-Siberian American Aborigines);
• Viking explorer Leif Ericson. The Vikings were the first Europeans proven to have landed in America (see Vinland);
• Indians, Vikings and various unproven voyagers like Saint Brendan, Zheng He, Prince Madoc, and many others (see Pre-Columbian trans-oceanic contact);
• Christopher Columbus, the first proven Old Worlder since the Vikings;
• other European explorers during the "Age of Exploration" (see European colonization of the Americas).
