John Ross Robertson (1841 -1918) was a Canadian newspaper publisher, politician, and philanthropist in Toronto. A firm advocate of amateur sport, he served as president of the Ontario Hockey Association. His battle to protect hockey from the influence of professionalism caused him to be called the "father of Amateur Hockey in Ontario." He worked especially hard to rid hockey of increasing violence both on and off the ice. The championship trophy of the Ontario Hockey League, the J. Ross Robertson Cup, is still named in his honour. He was inducted into the Hockey Hall of Fame in 1945.
