Dorion (French pronunciation: [dɔʁjɔ̃]) 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.

It disappeared in the 1994 election and its successor electoral district was Laurier-Dorion.

The electoral district was named in honour of a prime minister of the United Province of Canada, Antoine-Aimé Dorion.
