Deux-Montagnes is a provincial electoral district in Quebec, Canada, that elects members to the National Assembly of Quebec. It consists of the cities of Deux-Montagnes and Saint-Eustache. It was created for the 1867 election (and an electoral district of that name existed earlier in the Legislative Assembly of the Province of Canada).

The Autodrome Saint-Eustache was a motor sport complex in Saint-Eustache, Quebec, Canada. Established in 1965, it contained a 0.40 mi (0.64 km) paved oval and a 1.10 mi (1.77 km) paved road course with hot pits, grandstands and services. The oval circuit hosted NASCAR Whelen All-American Series weekly racing, with drivers racing for both the province (Quebec) and the rest of North America. Its premier event was the NASCAR Pinty's Series which raced at the track since the creation of the series. The track also formerly held CASCAR Super Series events. In an agreement with the City of Saint-Eustache, the property was sold to Hydro-Québec at the end of the 2019 racing season. The expanding infrastructure of the city of Saint-Eustache was cited as the main reason for the track's demise.
