Forêt-Ouareau Regional Park, Regional park in Matawinie, Canada.

Forêt-Ouareau Regional Park covers more than 150 km2 in the Matawinie RCM of Lanaudière, Quebec, within Notre-Dame-de-la-Merci, Entrelacs, Saint-Côme and Chertsey. The Ouareau River crosses it toward the southeast, and its relief includes the Grande-Ourse (660 m), Tête-Dure (645 m) and Mont 107 (635 m) mountains. Trails and sites are reached from five sectors: Massif, Grande-Jetée, Grande-Vallée, Pont Suspendu and Contreforts.

The park's name received official recognition from Quebec's toponymy commission on September 24, 2003. The designation was based on the Ouareau River, which appeared on survey maps dating to 1789.

The name Ouareau comes from an Algonquin word meaning "far away". It appears as "The river Lac Ouareau" on a 1789 map by surveyor William Rankins, and the toponym was made official on September 24, 2003, by the Commission de toponymie du Québec. The park is named after the Ouareau River, which crosses it toward the south-east.

The park divides into five separate sectors, each offering trails suited to different interests and fitness levels. Infrastructure includes hiking routes, winter activity areas, and designated climbing zones, all clearly marked for visitor navigation.

Climbing walls at Lac Blanc and along Murmures Trail operate through Quebec's mountain climbing federation system. These specialized areas allow climbers to practice their skills in a natural setting while staying within managed safety protocols.
