List of sovereign states and dependent territories in South America

There are 12 sovereign states and 3 non-sovereign dependent territories in South America. The continent is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean. North America and the Caribbean Sea lie to the northwest. South America has an area of approximately 17,840,000 square kilometres (6,890,000 sq mi), or almost 3.5% of Earth's surface. As of 2018, its population is more than 430 million, according to estimates of population in The World Factbook. South America ranks fourth among all continents in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America).^[1]

The border between North and South America is at some point in the Isthmus of Panama. The most common demarcation in atlases and other sources follows the Darién Mountains watershed that divides along the Colombia–Panama border where the isthmus meets the South American continent (see Darién Gap). Virtually all atlases list Panama as a state falling entirely within North America and/or Central America.^[2]
