The Exact Answer to How Many Countries in South America Revealed

Published 20 June 2026

South America’s borders are deceptively simple on a map, yet the question "how many countries in South America" triggers debates among geographers, historians, and diplomats. At first glance, the answer seems straightforward: 12. But scratch beneath the surface, and you’ll find territories contested by neighboring nations, overseas departments with ambiguous statuses, and microstates whose sovereignty is recognized by some but not all. Even the United Nations’ official count can vary depending on which dependencies or disputed regions are included. The confusion stems from how how many countries in South America is defined—whether by full UN recognition, geographical location, or political autonomy.

The ambiguity isn’t just academic. Territorial disputes in the region, like the long-standing conflict between Bolivia and Chile over access to the Pacific, or the status of French Guiana as an overseas department of France, prove that how many countries in South America isn’t just a trivia question. It’s a reflection of colonial legacies, 19th-century wars, and modern geopolitical maneuvering. For instance, Guyana’s recent oil boom has reignited tensions with Venezuela, which claims a vast portion of its territory under the name Guayana Esequiba. Meanwhile, the Falkland Islands (Islas Malvinas), though geographically part of South America, are a British Overseas Territory—leaving their inclusion in counts of how many countries in South America a matter of perspective.

What’s undisputed is that South America’s sovereign nations are a patchwork of cultures, economies, and political systems. From the Andean highlands to the Amazon rainforest, each country’s identity is shaped by its history—whether it’s Brazil’s Portuguese colonial past, the Inca empires that preceded modern Peru and Bolivia, or the military dictatorships that once ruled Argentina and Chile. Understanding how many countries in South America requires peeling back these layers, from the 1824 Gran Colombia dissolution to the 2020 independence of de facto regions like the Mapuche territories in southern Chile and Argentina. The answer isn’t just numerical; it’s a story of power, resistance, and shifting borders.

The Complete Overview of How Many Countries in South America

The confusion arises from two key factors: geographical inclusion and political recognition. Some sources expand the count to 14 by adding Guyana (often confused with its neighbor, Guyana) or Ecuador’s Galápagos Islands, which are technically a province but function as a quasi-autonomous entity. Others might argue for 15 if including the British Antarctic Territory (though it’s uninhabited and claimed by multiple nations). The most widely accepted figure, however, remains 12, based on the UN’s Geoscheme for Europe and the Americas. Yet, even this number isn’t set in stone. In 2011, the UN temporarily recognized South Sudan as a new country, but its inclusion in South America is irrelevant—proving that global recognition can shift overnight.

Historical Background and Evolution

The Monroe Doctrine (1823) and subsequent 19th-century wars—such as the War of the Pacific (1879–1884) between Chile, Bolivia, and Peru—further reshaped borders. Bolivia lost its coastline to Chile, while Brazil’s 1889 proclamation of the Republic ended the monarchy and solidified its territory. The 20th century brought additional changes: French Guiana remained under French control despite its South American location, Suriname gained independence from the Netherlands in 1975, and Guyana became a republic in 1966 after British rule. Even today, the question of how many countries in South America is influenced by these historical fractures. For instance, Venezuela’s claim to Guayana Esequiba (a third of Guyana’s land) hinges on an 1899 arbitration award that Guyana disputes, keeping the issue unresolved.

Core Mechanisms: How It Works

The Organization of American States (OAS) and UN Geoscheme use slightly different classifications. The OAS lists 35 member states, but only 12 are in South America. The UN’s Geoscheme groups South America separately from Central America and the Caribbean, reinforcing the 12-country consensus. However, how many countries in South America could expand if territories like the ABC Islands (Aruba, Bonaire, Curaçao) were considered—though they’re part of the Kingdom of the Netherlands. Similarly, the British Overseas Territory of South Georgia and the South Sandwich Islands lies near South America but is uninhabited. These exceptions highlight that how many countries in South America is as much about politics as it is about geography.

Key Benefits and Crucial Impact

The economic and military implications of how many countries in South America extend beyond borders. The Mercosur trade bloc (Argentina, Brazil, Paraguay, Uruguay, and Venezuela) integrates economies but excludes Chile and Colombia, showing how how many countries in South America can influence regional alliances. Meanwhile, disputed territories like Guayana Esequiba become flashpoints for resource conflicts. The 2023 Guyana-Venezuela standoff over oil drilling rights proved that even a minor adjustment to how many countries in South America can trigger international crises.

> "A map of South America is a palimpsest of empires—Spanish, Portuguese, British, Dutch—each layer erasing and redrawing the lines of statehood. The question of how many countries exist today is less about numbers and more about who controls the narrative of history." — Dr. María Elena Busso, Latin American Geopolitics Expert, University of Buenos Aires

Major Advantages

• Economic Diversity: The 12 countries in South America collectively dominate global markets in agriculture (Brazil), mining (Peru), and energy (Venezuela). This diversity mitigates risk for investors and ensures regional resilience.
• Strategic Biodiversity: The Amazon rainforest spans nine countries, making how many countries in South America a critical factor in climate policy. Deforestation disputes (e.g., Brazil vs. Bolivia) highlight the ecological stakes.
• Cultural Crossroads: From Andean music to Portuguese-influenced Carnival, the 12 nations create a cultural melting pot that attracts tourism and soft power influence.
• Geopolitical Balance: The region’s mix of leftist and rightist governments (e.g., Bolivia’s MAS vs. Chile’s center-right) ensures no single power dominates, stabilizing how many countries in South America as a check on hegemony.
• Resource Diplomacy: Countries like Chile (lithium) and Argentina (agriculture) use their unique assets to negotiate trade deals, proving that how many countries in South America translates to economic leverage.

Comparative Analysis

Future Trends and Innovations

Culturally, indigenous autonomy movements in Peru, Ecuador, and Colombia could lead to new semi-autonomous regions, blurring the lines of statehood. Economically, lithium-rich Argentina and Chile may form a new alliance, while Brazil’s Amazon policies will dictate whether the region remains a single ecological unit or fragments into competing interests. The answer to "how many countries in South America" in 2040 might not just be numerical—it could reflect a post-national era where sovereignty is shared or contested in ways we’re only beginning to imagine.

Conclusion

Yet, the number isn’t fixed. As climate change redraws coastlines, as indigenous groups demand self-rule, and as old empires reassert influence (see: China’s investments in Latin America), the map of South America will continue to shift. The next time someone asks "how many countries in South America", the answer might not be 12—or it might be, but with new caveats. One thing is certain: the story of how many countries in South America is far from over.

Comprehensive FAQs

Q: Why does the answer to "how many countries in South America" vary?

The count fluctuates because of territorial disputes (e.g., Guayana Esequiba), overseas departments (French Guiana), and geopolitical recognition. The UN uses a standard of 12, but some sources include disputed regions, raising the number. For example, if you count Western Sahara (African but often grouped with South America in some classifications), the number could rise to 13.

Q: Are the Falkland Islands part of South America?

Geographically, yes—they lie east of Argentina in the South Atlantic. However, they are a British Overseas Territory, not a sovereign country. Thus, they are not included in the 12-country count of how many countries in South America. Argentina claims them as Las Malvinas and considers them part of its territory.

Q: Why isn’t Brazil considered part of Central America?

Brazil is geographically and culturally part of South America. Central America consists of 7 smaller countries (Costa Rica, Panama, etc.) between Mexico and Colombia. Brazil’s size (largest in South America) and Portuguese heritage distinguish it from Spanish-speaking Central American nations.

Q: Could South America gain a 13th country in the future?

Unlikely in the short term, but two scenarios could change the count:
1. Western Sahara’s independence (if recognized by enough nations).
2. A new state emerging from indigenous autonomy movements (e.g., Mapuche territories in Chile/Argentina).
However, neither is imminent. The 12-country status is stable for now.

Q: How does the number of countries in South America compare to Africa?

Africa has 54 recognized sovereign states (the most globally), while South America has 12. The disparity stems from decolonization timelines—Africa’s nations gained independence later (post-WWII), while South America’s borders were largely set by the 19th century. Additionally, Africa’s colonial borders (drawn by Europe) created more artificial states.

Q: Are there any unrecognized countries in South America?

No fully sovereign, unrecognized countries exist in South America today. However, two notable cases involve disputed regions:

Q: Which South American country has the most disputed borders?

Venezuela has the most active border disputes:
1. Guayana Esequiba (with Guyana, over oil-rich territory).
2. Esequibo region (Venezuela’s claim is backed by a 1966 UN agreement but rejected by Guyana).
3. Historical claims over parts of Brazil and Colombia.
Chile also has disputes (e.g., Beagle Channel), but Venezuela’s conflicts are currently the most volatile.

Q: How does the number of countries in South America affect tourism?

The 12-country count makes South America a diverse but logistically complex destination. Travelers planning multi-country trips must account for visa requirements (e.g., Brazil’s strict entry rules), border crossings (some are poorly maintained), and language barriers (Portuguese in Brazil vs. Spanish elsewhere). However, the variety also makes it a unique global region—no other continent has such a mix of jungles, Andes, and urban megacities within 12 nations.

Q: Can a South American territory become independent?

It’s possible but rare. The last successful case was East Timor (2002), though it’s in Southeast Asia. In South America, French Guiana is the most discussed candidate—some local politicians advocate for independence, but France’s control over its economy (e.g., spaceport, gold mining) makes secession unlikely. Puerto Rico’s status in the Caribbean is a closer parallel, but it’s not in South America.
