Argenteuil—Papineau—Mirabel (formerly known as Argenteuil, Argenteuil—Papineau and Argenteuil—Deux-Montagnes) was a federal electoral district in Quebec, Canada, that was represented in the House of Commons of Canada from 1867 to 2015.

In 1882, the townships of Salaberry, Wolfe and Grandison were detached from Argenteuil and annexed to Terrebonne. In 1924, Argenteuil electoral district was redefined to consist of the County of Argenteuil.
