Saint-Elzéar (French pronunciation: [sɛ̃t‿ɛlzeaʁ]) is a municipality in Quebec, Canada.

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.

[1] 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.

[4] 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.
