Rousseau is a provincial electoral district in the Lanaudière and Laurentides regions of Quebec, Canada, that elects members to the National Assembly of Quebec. It notably includes the municipalities of Saint-Lin–Laurentides and Sainte-Julienne.

It was created for the 1981 election from parts of the Prévost, Joliette-Montcalm and L'Assomption electoral districts.

In the change from the 2001 to the 2011 electoral map, it gained Chertsey and Saint-Hippolyte from Bertrand, but lost L'Épiphanie (town), L'Épiphanie (parish), and the part of the city of L'Assomption that it formerly had to the L'Assomption electoral district.

In the change from the 2011 to the 2017 electoral map, it will gain Saint-Jacques, Saint-Liguori and Sainte-Marie-Salomé from Joliette and will lose Chertsey and Rawdon to Bertrand and Sainte-Sophie and Saint-Hippolyte to the new riding of Prévost.

It was named after botany professor Jacques Rousseau.
