Île Jésus (French for Jesus Island) is an island in southwestern Quebec, separated from the mainland to the north by the Rivière des Mille Îles, and from the Island of Montreal to the south by the Rivière des Prairies.
The second-largest (242 km²) island in the Hochelaga Archipelago (after the Island of Montreal), Île Jésus is the major component of the City of Laval, along with the Îles Laval and several other islands. The island is still rural in nature, with most of the urban area in the central region and along the south and west river banks.
