The Sutherland Cup is the ice hockey Ontario Junior "B" Provincial Championship trophy. The trophy was first awarded in 1934, and named in honour of former OHA and CAHA president, James T. Sutherland.

James Thomas Sutherland was a Canadian ice hockey administrator, and founding father of the game in Canada. Sutherland was a pioneer of hockey's early years, helping to develop amateur hockey, and spread the game's popularity throughout the country, and into the United States. He played in the inaugural season of the Ontario Hockey Association, and later coached and refereed the game. He founded the original Kingston Frontenacs, and later became president of the Ontario Hockey Association, and then the Canadian Amateur Hockey Association. He was instrumental in founding the Memorial Cup in 1919, and was at the forefront of the discussion on the origins of hockey.
