Ecuador is in South America. It lies on the continent's north-western Pacific coast, between Colombia to the north and Peru to the east and south, and the Equator that gives the country its name runs just north of the capital, Quito. Central America is a different region altogether: it is the narrow land bridge of seven countries, from Guatemala and Belize down to Panama, that ends where Panama meets Colombia, more than 800 km north of Quito. Ecuador shares no border with any Central American state, and the United Nations, the Andean Community and South American football's governing body all count it as South American, along with its Galápagos Islands far out in the Pacific.
Latitude 0°: Ecuador’s Position from Mitad del Mundo to Chimborazo
Ecuador spans roughly 2° north to 5° south of the Equator, making it the westernmost country that the line crosses. Its name is simply the Spanish word for the Equator. The modern republic took it from the Ecuador Department, a province created by Gran Colombia in 1824 out of the old Royal Audience of Quito, and the official title is still the República del Ecuador, the "Republic of the Equator".
The line itself passes about 26 km north of central Quito, at the Ciudad Mitad del Mundo ("Middle of the World City") in San Antonio parish. A 30-metre stone monument there commemorates the French Geodesic Mission of the 1730s, led by Louis Godin, Pierre Bouguer and Charles Marie de La Condamine, who came to measure a degree of latitude near the Equator and helped prove that the Earth bulges at its middle. Their line was later found to be off by about 240 m, which is why visitors with GPS units find latitude 0° a short walk from the monument.
Quito itself sits at 2,850 m (9,350 ft), which makes it either the highest or second-highest national capital in the world, depending on whether La Paz or Sucre is counted for Bolivia. That altitude tells you where Ecuador sits on the continent: in the northern Andes, the mountain chain that runs the full length of South America's western side and has no counterpart in Central America's volcanic spine.
The country's area is about 283,600 km² (109,500 sq mi) by the CIA World Factbook's count, including the Galápagos; Ecuador's own foreign ministry gives a smaller 256,370 km². Either way it is one of the smaller South American states, larger only than Uruguay, Suriname, Guyana and French Guiana. Its population is about 17.8 million, most of them mestizos. The mainland divides into three long strips. La Costa, the Pacific lowland, holds Guayaquil, the largest city, and the banana and rice plantations. La Sierra is the Andean highland of Quito, Cuenca and the volcano avenue. El Oriente is the Amazon rainforest east of the mountains, which drains towards Brazil and the Atlantic.
The highest of those volcanoes is Chimborazo, 6,263 m (20,548 ft) high in the Cordillera Occidental. Because it stands so close to the Equator, where the Earth's surface bulges outwards, its summit is the point on the planet farthest from the Earth's centre, further out even than the top of Everest. Cotopaxi, just south of Quito, is one of the highest active volcanoes in the world. All of them belong to the Andes, the defining backbone of South America.
Where Central America Ends: the Isthmus of Panama and the Darién
The confusion usually comes from treating "Central America" as a loose label for the tropical, Spanish-speaking countries near the Equator. Geographers use the term much more narrowly. Central America is a subregion of North America, bounded by Mexico to the north and Colombia to the south-east, and is usually defined as seven countries: Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama.
The dividing line between the two Americas is drawn at the Isthmus of Panama, the narrow strip of land between the Caribbean Sea and the Pacific that formed around 3 million years ago and joined the two continents. In political terms, the boundary follows the Colombia–Panama border through the roadless Darién forest. Everything south and east of it is South America. Ecuador is a full country further on, beyond the whole Pacific coast of Colombia: the straight-line distance from Quito to the Colombia–Panama frontier is around 830 km.
History has blurred this line in a few ways. From 1819 to 1831 Ecuador and Panama were both part of Gran Colombia, the republic built by Simón Bolívar's campaigns, and Panama remained a part of Colombia until it broke away in 1903. That is why Panama is sometimes described as the most South American of the Central American states, a question we look at in is Panama in North America or South America. Money adds to the mix. Ecuador adopted the US dollar as its official currency in 2000 after a financial crisis, El Salvador did the same in 2001, and Panama has used the dollar since 1904, so a traveller paying in dollars in Quito and Panama City might assume the two belong together. They do not: Ecuador's links run south along the Andes, not north across the isthmus.
Colombia and Peru: Two Borders Settled in 1916 and 1998
Ecuador has only two land neighbours, both South American. Its land boundaries total about 2,010 km, and it has around 2,337 km of coastline on the Pacific, including the Galápagos.
The northern border with Colombia runs for about 590 km from the Güepí River in the Amazon to the mouth of the Mataje River on the Pacific at Ancón de Sardinas Bay. It was fixed by the Muñoz Vernaza–Suárez Treaty of 15 July 1916, and the sea boundary that continues 200 nautical miles offshore was agreed in 1975. The line covers only a fraction of what the two countries once disputed after Gran Colombia broke up in 1830.
The southern and eastern border with Peru is much longer, about 1,420 km, and far more contested in its history. It runs from the Pacific along the Zarumilla River, across the Cordillera del Cóndor and through the Amazon to the Putumayo River. The Rio Protocol, signed in Rio de Janeiro on 29 January 1942 after the Ecuadorian–Peruvian War of 1941, was meant to settle it, with the United States, Brazil, Chile and Argentina as guarantors. Ecuador later rejected the treaty as it applied to the Cordillera del Cóndor, and fighting broke out again in the Paquisha incident of 1981 and in the Cenepa War from 26 January to 28 February 1995. The dispute was finally closed in 1998, when Presidents Jamil Mahuad and Alberto Fujimori signed the Brasilia Presidential Act. Both frontiers are mapped in detail in our countries that border Ecuador guide.
The Galápagos, 900–1,000 km Out in the Pacific
The one part of Ecuador that does not sit on the South American mainland is the Galápagos archipelago, a chain of volcanic islands straddling the Equator. Their distance from the mainland is usually given as 485 nautical miles, about 898 km, though some sources round it to about 1,000 km; the figure depends on which island and which point of the coast are measured. The islands form Galápagos Province, with three cantons named for the most populated islands, San Cristóbal, Santa Cruz and Isabela, and had a population of slightly over 33,000 in 2020.
Ecuador formally claimed and occupied the islands on 12 February 1832, two years after leaving Gran Colombia, while HMS Beagle's survey voyage, which brought Charles Darwin to the islands in 1835, was still under way. The official name in Ecuadorian state documents is the Archipiélago de Colón, given in 1892 for the four-hundredth anniversary of Columbus's first voyage. Because the islands are oceanic volcanoes rather than pieces of the continental shelf, some geographers group them with the Pacific islands of Oceania, which under strict definitions would make Ecuador transcontinental. In practice they are governed, counted and usually mapped as part of South America. None of this moves them closer to Central America; for the volcanic and ecological detail, see our Galápagos Islands geography guide.
CAN, CONMEBOL and UN Code 218
Every regional grouping Ecuador belongs to points south. Under M49, the UN's statistical coding system, Ecuador carries code 218 and sits in the South America subregion of Latin America and the Caribbean, next to Colombia, Peru, Bolivia, Brazil and the rest of the continent. The UN's Central America subregion is a separate list: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama and, in that scheme, Mexico.
Ecuador's own regional bloc is the Andean Community (Comunidad Andina, CAN). Bolivia, Chile, Colombia, Ecuador and Peru founded it as the Andean Pact under the Cartagena Agreement of 26 May 1969. Venezuela joined in 1973 and left in 2006, and Chile withdrew in 1976, leaving four members today: Bolivia, Colombia, Ecuador and Peru, with the secretariat in Lima. Ecuador is also an associate state of Mercosur, the South American trade bloc. It hosted the headquarters of the Union of South American Nations (UNASUR) at Mitad del Mundo until it announced its withdrawal from that organisation on 13 March 2019. None of these bodies includes a Central American country as a full member, whereas Panama, Costa Rica and their neighbours belong to the Central American Integration System instead.
Sport tells the same story. Ecuador joined FIFA in 1926 and CONMEBOL, the South American confederation, a year later, and it qualifies for the World Cup against Brazil, Argentina, Colombia and Peru, while Panama and Costa Rica play in CONCACAF with Mexico and the United States. Ecuador is also a founding member of the United Nations and the Organization of American States, the forums where it sits as one of the twelve sovereign countries of South America.
