The 10 Smallest Countries in the World

When we picture countries on a map, we tend to imagine vast territories. But some of the most fascinating nations on Earth are barely visible without a magnifying glass. Here are the 10 smallest countries in the world by land area, along with the remarkable stories that make each one unique.

The 10 Smallest Countries

1. Vatican City — 0.44 km²

The smallest country on Earth is entirely enclosed within Rome, Italy. Home to the Pope and the central government of the Roman Catholic Church, Vatican City has a population of around 800 people. Despite its size, it operates its own postal system, radio station, and the famous Swiss Guard.

2. Monaco — 2.02 km²

The world's most densely populated sovereign nation is a city-state on the French Riviera. Around 36,000 people live in just 2 km² of territory. Monaco has no income tax for residents, which helps explain why it attracts so many of the world's wealthiest individuals.

3. Nauru — 21 km²

This Pacific island nation is the world's smallest island country. Nauru grew wealthy in the 20th century through phosphate mining, but after reserves were exhausted, the country faced severe economic challenges.

4. Tuvalu — 26 km²

A Polynesian island nation in the central Pacific, Tuvalu's highest point is only 4.5 meters above sea level. That makes it one of the most threatened countries in the world as sea levels rise due to climate change.

5. San Marino — 61 km²

Completely surrounded by Italy, San Marino claims to be the world's oldest republic, founded in 301 AD. It has maintained its independence for over 1,700 years, largely through diplomacy rather than military strength.

6. Liechtenstein — 160 km²

One of only two doubly landlocked countries in the world (the other being Uzbekistan), Liechtenstein sits between Switzerland and Austria. Despite its tiny size, it has one of the highest GDP per capita in the world, driven by financial services and specialized manufacturing.

7. Marshall Islands — 181 km²

This Pacific archipelago of 29 atolls and 5 islands was a major World War II battleground. Like Tuvalu, it faces existential threat from rising sea levels, as most of its land sits less than 2 meters above the ocean.

8. Saint Kitts and Nevis — 261 km²

The smallest sovereign state in the Western Hemisphere, Saint Kitts and Nevis was the first Caribbean island colonized by Europeans (the British, in 1623). It gained independence from the UK in 1983.

9. Maldives — 298 km²

This Indian Ocean archipelago of about 1,200 coral islands is famous for its luxury resorts and its vulnerability to climate change. Its average ground elevation is just 1.5 meters above sea level, the lowest of any country.

10. Malta — 316 km²

An archipelago in the Mediterranean Sea with over 7,000 years of documented history, Malta was heavily bombed during World War II and awarded the George Cross by King George VI for its resistance. Today it is an EU member and popular tourist destination.

Why Do Micro-States Exist?

Many micro-states exist because of historical accidents: medieval treaties that were never undone, geographic isolation that protected small communities, or strong local identities that survived centuries of political change. In Europe, several tiny states emerged from the fragmentation of the Holy Roman Empire and maintained their independence through diplomacy rather than force.
