Rivière-du-Loup–Témiscouata is a provincial electoral district in Quebec, Canada, that elects members to the National Assembly of Quebec.

It is located in the Bas-Saint-Laurent region.

It notably includes the municipalities of Rivière-du-Loup, Témiscouata-sur-le-Lac, Saint-Antonin, Trois-Pistoles, Dégelis, Pohénégamook, Cacouna, Saint-Jean-de-Dieu, Saint-Hubert-de-Rivière-du-Loup and L'Isle-Verte.

It was created for the 2012 election from all of the former Rivière-du-Loup electoral district and part of the former Kamouraska-Témiscouata electoral districts; it also took Lac-des-Aigles and Biencourt from the Rimouski electoral district.

Effectively, the entire territory of the Témiscouata Regional County Municipality was added to the former Rivière-du-Loup electoral district.
