Saint-Elzéar is a municipality in Quebec, Canada. It is also known as Saint-Elzéar-de-Bonaventure to distinguish it from Saint-Elzéar in the Chaudière-Appalaches region.

Settlement of the place began in 1924, at the instigation of Elzéar Matte who was vicar general in Bonaventure at that time. That same year, the Saint-Elzéar Parish was founded and the Saint-Elzéar-de-Bonaventure Post Office opened.

The Municipality of Saint-Elzéar was formed on January 1, 1965, from territory ceded by the Municipalities of New Carlisle, Bonaventure, and Paspébiac-Ouest, as well as portions of unorganized areas.

In 2022, Saint-Elzéar received media attention after an Alert Ready notification concerning a shelter-in-place order for the municipality was sent to phones across the entire province of Quebec.
