How many countries are bordering Argentina?

Argentina borders five countries: Bolivia and Paraguay to the north, Brazil to the northeast, and Chile to the west and south, with the Atlantic Ocean forming its eastern boundary.

These neighbors give Argentina a wild mix of landscapes. You’ve got the Andes in the west, the Pampas’ endless grasslands in the center, and the Atlantic’s coastline to the east. Crossing between countries is pretty straightforward thanks to well-known border crossings like Los Libertadores or Paso Cardenal Samoré. According to the CIA World Factbook, Argentina’s total land border stretches about 11,800 kilometers (7,300 miles).

What country borders Argentina and only Argentina?

Chile is the only country that borders Argentina and no other country; it’s separated from Argentina by the Andes Mountains along the entire western frontier.

This border happens to be the third-longest international border worldwide, clocking in at roughly 5,300 kilometers (3,300 miles). The mountains are so rugged that travelers need special high-altitude crossings like Agua Negra or Los Libertadores. Chile and Argentina also share a maritime border in the South Atlantic and Pacific Oceans. As of 2026, these crossings remain vital for trade and tourism between the two nations.

How many South American countries border Argentina?

Argentina shares borders with five South American countries: Chile, Bolivia, Paraguay, Brazil, and Uruguay.

That makes Argentina one of the most connected countries in South America.

These connections boost regional trade and cultural exchange. The Encyclopaedia Britannica points out that Argentina’s borders reflect its diverse landscapes, from subtropical jungles in the northeast to arid deserts in the northwest.

What is the natural border between Argentina and Chile?

The Andes Mountains form the natural border between Argentina and Chile, creating a continuous divide along 5,300 kilometers of rugged terrain.

These mountains aren’t just a political line—they’re a climate divider too. The western side gets way more rain, while the eastern side stays drier. Major crossings like Los Libertadores (near Mendoza) and Cardenal Samoré (near Bariloche) let travelers navigate high-altitude passes. The Andes are actually the longest continental mountain range on Earth, spanning seven countries. According to National Geographic, this range shapes weather patterns across South America.

Argentina is considered one of the safer countries in South America for travelers, with relatively low violent crime rates in most regions.

The Overseas Security Advisory Council (OSAC) says violent crime against tourists is rare but recommends extra caution at night and in quieter spots. Rural areas and Patagonia? Usually super safe. Stick to common sense: don’t flash valuables, use licensed taxis or ride-sharing apps, and you’ll be fine.
