There are two Malbaie Rivers in the province of Quebec in Canada.
The Malbaie River in the Charlevoix region empties into the Saint Lawrence River at La Malbaie. Up until 1985, the river was used to transport logs downstream. The river flows through a steep valley known as Les Hautes Gorges. A forest of sugar maples and American elms which has remained largely undisturbed for hundreds of years is found in the gorge.
Le parc national des Hautes-Gorges-de-la-Rivière-Malbaie is home to Eastern Canada's tallest rock-faced cliffs. Designated a national park (of the province of Québec) in 2000, the 233-km² Hautes-Gorges is the centerpiece of the UNESCO Charlevoix biosphere reserve.
The Malbaie River in the Gaspé Peninsula empties into the Baie de la Malbaie on the Gulf of Saint Lawrence. A barachois has formed at the mouth of the river. The salt marshes found there are home to the Yellow Rail and Nelson's Sharp-tailed Sparrow. The river also provides spawning habitat for Atlantic Salmon. The Nature Conservancy of Canada has initiated a project to protect this area.
