Taillon is a provincial electoral district in the Montérégie region of Quebec, Canada that elects members to the National Assembly of Quebec. It comprises part of the borough of Le Vieux-Longueuil of the city of Longueuil.
It was created for the 1966 election from Verchères and Chambly electoral districts.
It was named after former Quebec Premier Louis-Olivier Taillon who was in power for four days in 1886 and from 1892 to 1896. It is best known as the riding of Parti Québécois founder René Lévesque, who served as premier from 1976 to 1985.
For the better part of four decades after the PQ seized it in 1976, Taillon was a stronghold for both the PQ and the sovereigntist cause. In the 1995 Quebec referendum it voted 61% for Quebec to separate. However, in 2018, the Coalition Avenir Québec narrowly won it amid its near-sweep of Montérégie.
This riding has elected the following members of the National Assembly:
