Trois Rivières (provincial electoral district)

Trois-Rivières is a provincial electoral district in the Mauricie region of Quebec, Canada that elects members to the National Assembly of Quebec. It includes part of the city of Trois-Rivières, including most of the territory of the city as it existed prior to its 2002 amalgamation and expansion.

It was created for the 1867 election, and an electoral district of that name existed even earlier: see Trois-Rivières (Lower Canada) and Trois-Rivières (Province of Canada).

In the change from the 2001 to the 2011 electoral map, its border with the Maskinongé electoral district was adjusted, resulting in simultaneously gaining and losing different parts of the city of Trois-Rivières.
