The Sturgeon River is a river that springs near Lady Evelyn-Smoothwater Provincial Park in the Timiskaming District in Ontario, Canada. It flows in a mostly south-easterly direction through Sudbury and Nipissing Districts before it empties into Lake Nipissing on the north shore. with some 65 sets of rapids, mostly rated CI and CII that can be run all season.
Ontario Power Generation operates a hydroelectric plant on the river at Crystal Falls. From 1848 to 1879, the Hudson's Bay Company operated a fur trading post called Sturgeon River House at the mouth of this river (now turned into a local museum). Up until the middle of the 20th century, the river was used to transport logs to sawmills on Lake Nipissing. The lower part of the river is prone to flooding. In 1979 the area around the community of Field experienced a disastrous flood that prompted all residential homes to be relocated.
