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.

The Sutherland Cup is now the championship trophy of the Greater Ontario Hockey League. Until 2007, the Cup served as an interleague provincial championship. From 1976 until 1978, as many as eight leagues competed for the Sutherland Cup in a massive playdown structure that took months to complete.

There is no National Championship for Junior B hockey in Canada, similar championships are held in Western Canada (Keystone Cup), Quebec (Coupe Dodge), Eastern Ontario (Barkley Cup), and Atlantic Canada (Don Johnson Memorial Cup)—leaving five teams at the end of each year with a shared claim to being the best Junior B team in Canada.
