Flags of international organizations
The UN, the EU, NATO, the Olympics and more: flags that stand for groups of countries rather than one.

Organization flags have to belong to everyone and no one, so they lean on maps, globes, rings and olive branches, and on colours that don’t favour any member.
Worldwide
United Nations
The world seen from above the North Pole, in a wreath of olive branches.
Olympics
Five rings, designed by Pierre de Coubertin in 1913.
Red Cross
Switzerland’s flag with the colours reversed, honouring the movement’s Swiss founders.
Red Crescent
The Red Cross’s equal, first used by the Ottoman Empire in the 1870s.
OPEC
The organisation’s logo in white on light blue, the letters of its name drawn as rounded shapes around a central stem.
Organisation of Islamic Cooperation
The emblem on white: a globe drawn in green lines with the Kaaba at its centre, cradled by a green crescent. It replaced a green flag in 2011.
Antarctic Treaty
A white map of Antarctica with lines of longitude, on dark blue.
Regional
European Union
Twelve gold stars, a number that has never matched the membership: it stands for completeness.
NATO
A compass rose, for the common path of its members.
Nordic Council
A stylised swan, the Nordic countries’ shared symbol.
Commonwealth of Independent States
White stripes rising and curling outward round a gold disc, on blue, standing for equal partnership, unity, peace and stability.
Organization of Turkic States
The four founding members combined: turquoise from Kazakhstan’s flag, the sun from Kyrgyzstan’s, the star from Azerbaijan’s and the crescent from Turkey’s, inside an eight-pointed Seljuk star added in 2024.
Arab League
The League’s emblem on green: a crescent around its Arabic name, inside a wreath of olive branches and a chain of 22 links, usually said to stand for its 22 members.
Gulf Cooperation Council
The council’s emblem on green: a hexagon for the six members, holding a map of the Arabian Peninsula, ringed by the Bismillah and the council’s name in Arabic.
African Union
A map of Africa inside a ring of gold stars.
Organization of American States
The seal on blue: the flags of all the member states on gold poles inside a white circle; each new member’s flag is added to it.
CARICOM
Two linked Cs for the Caribbean Community.
