Chambly—Borduas (also previously known as Chambly and Chambly—Verchères) was a federal electoral district in the province of Quebec, Canada, that was represented in the House of Commons of Canada from 1867 to 1935, and from 1968 to 2015. Created by the British North America Act of 1867, its name was changed in 1893 to "Chambly—Verchères". In 1933, it was amalgamated into the Chambly—Rouville and Richelieu—Verchères electoral districts. The district was re-created in 1966 from Chambly—Rouville, Châteauguay—Huntingdon—Laprairie, and Richelieu—Verchères. Its name was changed in 2003 to "Chambly—Borduas". In 2015, most of the district became part of Beloeil—Chambly, while small parts of it joined Montarville and Pierre-Boucher—Les Patriotes—Verchères.

It initially comprised the Parishes of Boucherville, Longueuil, St. Bruno and Chambly.

Julie, Verchères, Contrecoeur, Ste. Théodosie, St. Antoine, St. Marc and Beloeil.

In 1924, it was redefined to consist of the Counties of Chambly and Verchères including the Cities of Longueuil and St. Lambert.

When it was recreated in 1966, it was defined to consist of:

• the City of Chambly;
• the Towns of Beloeil, Boucherville, Saint-Bruno-de-Montarville and Saint-Hubert;
• the Counties of Chambly and Verchères;

• in the County of Laprairie: the municipality of Notre-Dame;

• the Towns of Carignan, Marieville, Richelieu, and Saint-Bruno-de-Montarville;
• in the County of Rouville: the parish municipalities of Notre-Dame-de-Bon-Secours, Sainte-Marie-de-Monnoir and Saint-Mathias.

In 1987, it was redefined to consist of:

• in the County of Verchères: the Village Municipality of McMasterville;
• in the County of Rouville: the parish municipalities of Notre-Dame-de-Bon-Secours and Saint-Mathias.

In 1996, it was redefined to consist of:
