The Sault Ste. Marie Marlboros, also known as the Canadian Soo and Soo Algonquins, was a professional ice hockey team from Sault Ste. Marie, Ontario, Canada. It was the lone Canadian entry in the International Hockey League of 1904–1907, and one of the first, if not the first, openly professional hockey teams in Canada.

The league was formed at the Conference of Hockey Clubs in American Cities in Chicago, Illinois, on November 5, 1904. The Canadian Soo was represented by J. P. Mooney and J. C. Boyd. The Canadian representatives presented a revenue-sharing proposal at the meeting. The idea put forward was that gate receipts should be split 60/40 home/visiting team with a minimum guarantee also in place so that the visiting team's expenses would be met. The proposal was accepted and the league was formed.
