The six official languages of the United Nations are Arabic, Chinese, English, French, Russian, and Spanish.

UN delegates may choose to speak in any of the  official languages and their speech will be simultaneously interpreted into the other five. Similarly, most official UN documents are written in all six of these languages. Occasionally, a delegate may decide to speak in a non-official tongue. At these times, the representative body is required to provide either an interpretation or a written text of the statement in one of the official languages.
