United Nations Messenger of Peace is a special post-nominal honorific title of authority bestowed by the United Nations to "distinguished individuals, carefully selected from the fields of art, music, literature and sports, who have agreed to help focus worldwide attention on the work of the United Nations." Globally, present and past messengers of peace are the only public figures that are or may be legally and diplomatically known as a "United Nations Goodwill Ambassador". Other United Nations goodwill ambassador programmes in the UN system participants assign their title of authority (commission) using the agency name or patent program acronym or abbreviation such as: UN Women Goodwill Ambassador; UNICEF Goodwill Ambassador; UNESCO Goodwill Ambassador; UNAIDS Goodwill Ambassador; and other legal designations following their name.
