Terrasse-Vaudreuil (French pronunciation: [tɛʁas vodʁœj]) is a small municipality on Île Perrot, just west of Montreal Island in Quebec, Canada.

At the beginning of the 20th century, Terrasse-Vaudreuil was the site of a large powder magazine.

[1] In 1948, its post office opened under the name Terrasse-Vaudreuil, in reference to its location on Lake of Two Mountains and its view towards Vaudreuil Bay and the town of Vaudreuil.

In the 1950s, it began to see rapid residential development.
