The Shamrock Summit was a summit meeting that took place in Quebec City, Quebec, Canada on 17-18 March 1985. It was a meeting between Prime Minister of Canada Brian Mulroney and President of the United States Ronald Reagan.
It was nicknamed the "Shamrock Summit" because both leaders had an Irish background. The meeting is well known because both leaders began to sing the song "When Irish Eyes are Smiling" with their wives at the Grand Théâtre de Québec in Quebec City at the end of the summit. The leaders discussed military, environment and free trade issues.
The event caused controversy in Canada and Mulroney was widely criticized by the Canadian media and the public for "humiliating" Canada by his display of affection for the Reagan's and the United States.
