Donald Stewart Johnson (March 25, 1930 – May 12, 2012) was a Canadian sports executive. He was elected president of the Newfoundland Amateur Hockey Association (NAHA) in 1966, sought to expand minor ice hockey in Newfoundland and negotiated for the NAHA to become a member of the Canadian Amateur Hockey Association (CAHA). He was elected president of the CAHA in 1975, resolved internal disagreement over the jurisdiction of junior ice hockey, avoided the withdrawal of the Western Canada Hockey League and sought a new professional-amateur agreement with the National Hockey League and World Hockey Association. He was part of negotiations to end the Canada men's national ice hockey team hiatus from the Ice Hockey World Championships and the Olympic Games, in exchange for International Ice Hockey Federation approval of the 1976 Canada Cup. He established a long-term sponsorship to improve the National Coaching Certification Program, twice visited China with a Canadian amateur team for instructional tours and arranged an exchange for Chinese players and coaches to attend training camps in Canada. He was chairman of the 1978 World Junior Ice Hockey Championships as the CAHA past-president, and was posthumously credited by Hockey Canada for playing an important role in Canada's return to international competitions and improving Canada's hockey reputation.
