Michael G. Barnett (born October 9, 1948 in Olds, Alberta) is a Canadian ice hockey executive currently serving as Senior Advisor to the President-General Manager of the New York Rangers. He is best known in the world of hockey as a former agent representing sports icon Wayne Gretzky for two decades. He was listed among the "100 Most Powerful People In Sports" by The Sporting News on six occasions from 1994 to 2000. During his 12 years as President of International Management Group's hockey division, Barnett represented a who's who of the National Hockey League. Barnett negotiated the playing and marketing contracts for Wayne Gretzky, Brett Hull, Jaromir Jagr, Sergei Fedorov, Paul Coffey, Joe Thornton, Mats Sundin, Lanny McDonald, Grant Fuhr, Marty McSorley, Alexander Mogilny, Owen Nolan, Daniel Sedin and Henrik Sedin and numerous others. Whatever the form of contract, Barnett's creativity was legendary. His ingenuity in finding language that challenged the NHL's Collective Bargaining Agreement, in finding products and companies for his clients that were groundbreaking in their launches, and his perpetual attention to the public relations of his clients, were all hallmarks of his career in athlete representation. Following his two-decades as one of the most highly regarded agents in all of sports, Barnett went on to become the General Manager of the Phoenix Coyotes in the National Hockey League.
