List of official languages of international organizations

This is a list of official languages of international organizations. Different organizations sometimes refer to their principal languages of administration and communication as "working languages", while others refer to these as being "official". No distinction is made here, except where an organization itself, distinguishes between its official and working languages.

English and French are often regarded as the symbolic official languages, although the former has gained prominence in recent years.

International
According to a recent study of multilingualism in 13 major international organizations (Commonwealth, ICC, ILO, IMF, IOC, IPU, ITU, OECD, UN, UPU, WB, WHO, and WTO), English is an official language in almost all (12). This is followed by French (10); Spanish (6); and Arabic, Chinese, and Russian (3 each). Interpretation is offered in Japanese and German as well for 2 organizations.

The six official languages of the United Nations reflects the languages of the permanent members of the Security Council (Chinese, English, French, and Russian), in addition to Arabic and Spanish. Another study found that the percentage of each language used at each United Nations meeting in 2010 was distributed as follows: English (98%), French (87%), Spanish (34%), Russian (10%), Arabic (7%), and Chinese (3%).
