The Blanche River (French: rivière Blanche, pronounced [ʁivjɛʁ blɑ̃ʃ]) is a stream flowing in the municipalities of Saint-Ubalde, Saint-Thuribe, Saint-Alban and Saint-Casimir, in Portneuf RCM, Capitale-Nationale, Quebec, Canada.

[1] The White River flows mainly in an agricultural environment, while passing near the villages of Saint-Ubalde and Saint-Casimir.

An undulating plain marks the region of Saint-Casimir (Quebec).

To the south, the hills are gneissic rocks (Clark and Globensky 1975: 10)[2] belonging to the Laurentian highlands called the “Petite Laurentides of Batiscan”.
