The Blanche river (French: rivière Blanche, pronounced [ʁivjɛʁ blɑ̃ʃ], lit. 'White River') is a tributary of the Bourbon River which flows into the Bécancour River.

The Blanche river flows in the municipalities of Saint-Pierre-Baptiste, Laurierville (Sainte-Julie sector) and Plessisville, in the L'Érable Regional County Municipality (MRC), in the administrative region of Centre-du-Québec, in province of Quebec, in Canada.

The main neighboring hydrographic slopes of the Blanche River are:

The Blanche River has its source at Lac Camille (length: 0.8 kilometres (0.50 mi); altitude: 284 metres (932 ft)), located in Saint-Pierre-Baptiste. This lake is located 6.2 kilometres (3.9 mi) south of the village of Laurierville and 10.7 kilometres (6.6 mi) east of downtown Plessisville.

From its source, the Blanche River flows on 8.3 kilometres (5.2 mi) in the following segments:

• 0.2 kilometres (0.12 mi) westward, up to the municipal limit of Laurierville (Sainte-Julie sector);
• 0.8 kilometres (0.50 mi) towards the west, crossing the southern part of the territory of Laurierville¸ (Sainte-Julie sector);
