The name "Deux-Montagnes" dates to 1674 when it was given to the lake that stands in front of Deux-Montagnes, and to the seigneury which stood north of the lake. Originally known as "Saint-Eustache-sur-le-Lac" when it was founded in 1921, it changed its name to Deux-Montagnes in 1963.
The municipality has two commuter train stations, on the Deux-Montagnes Line: Deux-Montagnes and Grand-Moulin.
