Flags of Antarctica

Many flags have flown over Antarctica in the 200 years since it was first sited. Historically and currently, national flags are the most common flags on the continent. While they were previously used for territorial claims, since the adoption of the Antarctic Treaty in 1959 most national flags are used to signal the affiliation of a particular station or vessel. This page documents the other flags associated with the continent, though it is by no means exhaustive. If you have additions or corrections, please contact us.

Continental Flags

The Emblem of the Antarctic Treaty

In 2002, the Antarctic Treaty Committee Meeting adopted an emblem to “provide a clear identity to the work of the ATCM and its Secretariat." which is sometimes used as a flag. International law recognizes the Antarctic Treaty System’s authority over the continent, meaning that it is the only flag to enjoy “official” status. As stated in the decision to adopt it, the emblem represents the treaty, not the continent. The decision also specifies that it may be used only by the ATCM and its Secretariat, or those operating with their authority.

 

Other Antarctic Flag Proposals

Several other flags have been proposed as a broader symbol of the continent and the people connected to it. None of these flags have any form of official status, and none are currently in common use on the continent. Click the images to view details and source links.

Territorial Flags

Seven countries have made eight claims to parts of Antarctica. Of those claims, four have flags officially adopted by their respective national governments. The remainder use the national flag as the symbol of their claimed territory. Click the images to view details and source links.

 

Historic Flags

Several expeditions have flown their own flags during their time on the continent. These flags were always accompanied by the flag of the expedition's country of origin. Click the images to view details and source links.

 

Expedition Flags

Sledge Flags

Sledge flags were a relatively short-lived custom of British polar explorers first used in 1850 on an Arctic expedition to find Sir John Franklin's lost expeditionIn the style of naval ships (the expedition was mounted by the Royal Navy and crewed by seamen), each sledge was given a flag, as well as a name and motto. This tradition carried on through the Heroic Age of Antarctic Exploration. There are several surviving versions of flags from Scott and Shackleton's expeditions. Most were pennants, with a few notable exceptions such as Shackleton's rectangular flag.

Marker Flags

Flags are used to mark trails, depots, and other sites around Antarctica. These flags are usually solid colors, often with reflective patches for maximum visibility. The meaning of a particular color of flag varies across time and location, but they most often communicate a level of safety. In the US Antarctic Program sites, for example, red and green flags both mark paths that are safe to traverse while black flags mark dangerous obstacles such as ice crevasses. 

 

Micronational Flags

 

Because of the large unclaimed territory in Antarctica, dozens of people have attempted to claim sovereignty in the form of micronations. These claims are explicitly forbidden in the Antarctic Treaty and are not recognized by any world government or major international organization. They exist almost exclusively online, although some have their own royal titles, currencies, and passports. Almost all have their own flag.

The flag of the Antarctic Micronational Union, like Graham Bartram's design, appears to be UN-inspired.

Scottish National Antarctic Expedition Flag

The flag of the 1902-1904 Scottish National Antarctic Expedition features the Scottish saltire with the initials of the expedition. Jessie Bruce made this for her husband, expedition leader William Bruce, to take on his journey south.
