UNTERM is a multilingual database for official terminology relevant to the work of the United Nations. It is a public website used by UN delegates and staff, as well as other users who are interested in the work and activities of the United Nations around the world.

Official terminology is provided in the six official languages of the United Nations — Arabic, Chinese, English, French, Russian and Spanish — in line with the General Assembly mandate on multilingualism.

UNTERM contains terminology entries from entities across the UN system. To ensure consistency across the UN system, the database is managed by UN language staff specialized in each subject.
