Saint-Paul-de-l'Île-aux-Noix (French pronunciation: [sɛ̃ pɔl də lil o nwa]) is a municipality in southern Quebec, Canada located in the administrative area of the Montérégie.

The name of this municipality was chosen to pay tribute to Monsignor Paul Bruchési, who had just been consecrated Archbishop of the Diocese of Montreal in 1897.

It refers to both a military establishment dating back to 1759 and a stretch of land opposite the municipality, and highlights the large number of walnut trees that once covered the island.

[1] The South Shore Protestant Regional School Board previously served the municipality.
