Montarville () is a provincial electoral district in the Montérégie region of Quebec, Canada that elects members to the National Assembly of Quebec. It consists of the municipalities of Boucherville and Saint-Bruno-de-Montarville, both of which are part of the urban agglomeration of Longueuil.
It was created for the 2012 election from parts of the Marguerite-D'Youville and Chambly electoral districts.
Marguerite-D'Youville, which ceased to exist, consisted of Boucherville and Sainte-Julie. To create Montarville, Sainte-Julie was moved to the Verchères electoral district and Saint-Bruno-de-Montarville was taken from Chambly.
