The du Lièvre River (Rivière du Lièvre in French) is a river in western Quebec which flows south from the Mitchinamécus reservoir and empties into the Ottawa River at Masson-Angers. The river is 330 km in length and drains an area of 10,400 km². The river's name comes from the French word for hare.

Tributaries of this river include the:

• Mitchinamécus River
• Kiamika River

The river flows through the communities of:

• Mont-Laurier
• Notre-Dame-de-Pontmain
• Notre-Dame-du-Laus
• Val-des-Bois
• Notre-Dame-de-la-Salette
• Glen Almond (municipality L'Ange-Gardien)
• Buckingham now part of Gatineau

At one time, the river was used to transport logs downstream to sawmills located near the river's mouth. In 1928, a paper mill was built near the mouth of the river. On December 18, 1998, this mill was bought from Industries James Maclaren Inc. by private investors and became Papier Masson Ltee. In turn, the White Birch Paper Company bought it in January 2006.

There are a number of hydroelectric plants on the river, as well as large and viable deposits of Uranium ore in the district.
