Gordon Renwick (born February 13, 1935) is a Canadian retired ice hockey administrator and businessman, who served as president of the Galt Hornets, president of the Canadian Amateur Hockey Association (CAHA), and then vice-president of the International Ice Hockey Federation (IIHF).
Renwick led the Hornets to Allan Cup championships in 1969 and 1971.
His travels to the Ahearne Cup in Europe led to him opening the door for European teams playing tournaments in North America, and his role as a Chef de Mission for these events.
Renwick was the founding chairman of the Wrigley Cup midget hockey tournament in 1974, and then became vice-president of the CAHA in 1975.
He served as president of the CAHA from 1977 to 1979, during a time when the CAHA battled with the World Hockey Association over junior-aged players, and struggled with Hockey Canada and the Government of Canada, for control of international hockey.
During his time as president, the CAHA began the process of recognizing women's ice hockey in Canada, and implemented rules for mandatory safety equipment for youths.
Renwick was the last elected president of the CAHA, which transitioned to having a full-time president in 1979.
Renwick later served eight years as vice-president of the IIHF, implementing bookkeeping and accounting reforms, and was responsible for marketing and sponsorship of international events including the Canada Cup, and the World Cup of Hockey.
He also served as the chairman of the IIHF committees for rules, by-laws and statutes, and helped negotiate National Hockey League involvement in the Winter Olympic Games.
He was inducted into the IIHF Hall of Fame in 2002, received the Order of Hockey in Canada in 2012, and is the namesake of the Renwick Cup.
