Upper Madawaska River Provincial Park, Provincial park along Madawaska River in South Algonquin, Canada.

Upper Madawaska River Provincial Park is a waterway-class provincial park in South Algonquin, Nipissing District, Ontario. It consists of a strip of land along both shores of the Madawaska River between the communities of Whitney and Madawaska, upstream of and not contiguous with Lower Madawaska River Provincial Park. A former Ottawa, Arnprior and Parry Sound Railway corridor runs along part of the river and is now a rail trail within the park.

The park takes in the corridor of the abandoned Ottawa, Arnprior and Parry Sound Railway, which ran along the Madawaska River. That rail line is now used as a multi-use trail within the park. The park itself protects the river's shoreline from Whitney to Madawaska.

The park's name comes from the Madawaska River, whose Algonquin-derived name is shared by the river, the village at its northern end and the park itself. The corridor is now used mainly for whitewater kayaking and canoeing, and the old railway line along the river serves as a multi-use trail.

The park is a non-operating provincial park with no facilities or services, so paddlers must be self-sufficient. It runs along both shores of the Madawaska River between the communities of Whitney and Madawaska. A rail trail follows the former Ottawa, Arnprior and Parry Sound Railway corridor beside part of the park.

The park is a non-operating waterway-class protected area, meaning it has no facilities or services at all. Its rail trail follows the former Ottawa, Arnprior and Parry Sound Railway corridor, abandoned before being incorporated into the park.
