The Cathedral of St. Francis Xavier (French: Cathédrale Saint-François-Xavier) is the cathedral church of the Roman Catholic Diocese of Chicoutimi, Quebec, Canada.

It is located at 514, rue Racine Est in the Saguenay borough of Chicoutimi, overlooking the old port area of the town.

The current structure is the fourth church to occupy this site and the third to serve as cathedral for the diocese.

The current sanctuary opened in 1922 and was designed by architects Rene-P. Lemay, Armand Gravel and Alfred Lamontagne in the Renaissance revival style.
