Bellechasse is a provincial electoral riding in the Chaudière-Appalaches region of Quebec, Canada which elects members to the National Assembly of Quebec. It notably includes a section of the city of Lévis as well as Saint-Henri, Saint-Anselme, Lac-Etchemin, Sainte-Claire, Beaumont, Saint-Charles-de-Bellechasse, Saint-Raphaël and Saint-Gervais.
It was created for the 1867 election, and electoral districts of that name existed even earlier: see Bellechasse (Province of Canada) and Bellechasse (Lower Canada).
