This is a list of UNICEF Goodwill Ambassadors, who work on behalf of the United Nations Children's Fund.
Danny Kaye was the first to hold the position, with the title of Ambassador-at-Large granted in 1954. Other celebrities have followed, acting as international, regional or national ambassadors, depending on their profile, interests, and desired level of responsibility. The goal of the program is to allow celebrities with a demonstrated interest in UNICEF issues to use their fame to draw attention to important issues. This may take the form of public appearances and talks, visits to troubled regions, which draw attention from the media, and use of their political access to advocate UNICEF causes.http://www.unicef.org/people/people_ambassadors.html
