Dorion was a provincial electoral district in the province of Quebec, Canada.
It corresponded to the Villeray neighbourhood in Montreal.
It was created for the 1966 election from parts of Montréal-Outremont, Montréal–Jeanne-Mance and Montréal-Laurier electoral districts. Its final election was in 1989. It disappeared in the 1994 election and its successor electoral district was Laurier-Dorion.
A Montréal-Dorion district also existed from 1912 to 1939.
The electoral district was named in honour of a prime minister of the United Province of Canada, Antoine-Aimé Dorion.
