The AACTA International Award for Best Supporting Actor is an accolade given by the Australian Academy of Cinema and Television Arts (AACTA), a non-profit organisation whose aim is to "identify, award, promote, and celebrate Australia's greatest achievements in film and television". The award is presented at the annual AACTA International Awards, which rewards achievements in feature films, regardless of the country the film was made. The winners and nominees are determined by the international chapter of the Academy, which comprises eighty members of Australian filmmakers and executives. It was first handed out by the Academy in 2013 (for films released in 2012) as a discretionary prize, with Robert De Niro being the first recipient.
