Who Owns Antarctica?
Antarctica does not belong to any single country. Instead, it is governed by the Antarctic Treaty System, signed in 1959 by multiple countries. The treaty:
- Bans military activity and territorial claims.
- Promotes scientific research and international cooperation.
- Protects the environment and prohibits resource exploitation.
List of Countries in Antarctica: Who Owns the Frozen Continent?
Antarctica is the fifth-largest continent and the coldest, driest, and windiest place on Earth. It is a vast, icy landmass covering about 14 million square kilometers, almost twice the size of Australia
Unlike other continents, Antarctica has no countries or permanent human settlements. Instead, it is governed by an international agreement called the Antarctic Treaty System, which prevents any nation from claiming ownership and promotes scientific cooperation.
However, seven countries have made territorial claims over parts of Antarctica, though these claims are not widely recognized. Some areas even overlap. Below is a list of the countries that have claimed portions of Antarctica and the territories they assert.
Countries That Have Made Claims in Antarctica
| Country | Territorial Claim in Antarctica | Year of Claim |
|---|---|---|
| Argentina | Argentine Antarctica | 1943 |
| Australia | Australian Antarctic Territory | 1933 |
| Chile | Chilean Antarctic Territory | 1940 |
| France | Adélie Land | 1924 |
| New Zealand | Ross Dependency | 1923 |
| Norway | Queen Maud Land & Peter I Island | 1939 |
| United Kingdom | British Antarctic Territory | 1908 |
Unclaimed and Overlapping Areas
- Marie Byrd Land is the largest unclaimed territory in Antarctica. No country has officially claimed this vast, icy region.
- The claims of Argentina, Chile, and the UK overlap in some regions.
- The United States and Russia have not made official claims but reserve the right to do so in the future.
The Antarctic Treaty System
In 1959, 12 countries signed the Antarctic Treaty, agreeing that:
- No new territorial claims can be made.
- The continent must only be used for peaceful and scientific purposes.
- Military activity and resource exploitation are prohibited.
- Environmental protection is a top priority.
Today, over 50 countries have joined the treaty, making Antarctica a unique international zone dedicated to research.
Geographical and Climatic Features of Antarctica
- Coldest Temperature: The lowest recorded temperature on Earth, -128.6°F (-89.2°C), was measured at Vostok Station.
- Ice Coverage: About 98% of Antarctica is covered in ice, containing nearly 70% of the world’s freshwater.
- Dry Valleys: Some regions, like the McMurdo Dry Valleys, receive almost no precipitation, making them one of the driest places on Earth.
Conclusion on the list of countries in Antarctica
While Antarctica has no official countries, several nations have territorial claims based on historical exploration. However, thanks to the Antarctic Treaty, the continent remains a place for science, cooperation, and environmental conservation rather than political control.
Interesting Facts About Antarctica

- Hidden Lakes: Scientists have discovered subglacial lakes under the ice, such as Lake Vostok, which has been sealed off for millions of years.
- Midnight Sun & Polar Night: During summer, the sun never sets, while in winter, it remains dark for months.
