Which countries claim Antarctica?

Several countries lay claim to different regions of Antarctica. Here are the countries with territorial claims in Antarctica as recognized by the Antarctic Treaty Consultative Meeting (ATCM):

1. Argentina: Argentina claims a region known as the "Argentine Antarctica," or "Antártida Argentina," which overlaps with British and Chilean claims.

2. Australia: Australia claims the Australian Antarctic Territory (AAT), which includes all land between 160 degrees east longitude and 44 degrees 38' east longitude, south of 60 degrees south latitude.

3. Chile: Chile claims the Chilean Antarctic Territory (Territorio Antártico Chileno), which overlaps with Argentine and British claims.

4. France: France claims the Adélie Land (Terre Adélie), located between 136° 11' east longitude and 142° 02' east longitude.

5. New Zealand: New Zealand claims the Ross Dependency (Ross Dependency), located between 160° east longitude and 150° west longitude, south of 60° south latitude.

6. Norway: Norway claims Queen Maud Land (Dronning Maud Land) and Peter I Island, located between 20 degrees west longitude and 45 degrees east longitude.

7. United Kingdom: The United Kingdom lays claim to the British Antarctic Territory (BAT), which includes the Falkland Islands and South Georgia and the South Sandwich Islands, in addition to the Antarctic Peninsula and the Weddell Sea.

It's important to note that none of these claims are universally recognized, as not all countries recognize the Antarctic territorial claims made by other nations. The Antarctic Treaty, signed in 1959, prohibits any new territorial claims in Antarctica, and it sets aside Antarctica for peaceful purposes and scientific research.
