The Soulanges Canal is an abandoned shipping canal in Quebec, Canada. It follows the north shore of the Saint Lawrence River between Pointe-des-Cascades and Coteaux-Landing, bypassing the rapids between Lake Saint-Louis and Lake Saint-Francis. In between, it passes through the towns of Les Cèdres and Coteau-du-Lac. It superseded the first Beauharnois Canal which was on the south shore of the Saint Lawrence. It is 23 kilometers (14 mi) long and had a 4.3 metres (14.1 ft) draught. Five locks measuring 85.3 m (280 ft) x 14 m (46 ft) give a total rise of 25 meters (82 ft).
Today, a popular cycling path follows the route of the canal. There are plans to reopen the canal to pleasure boats. The mission of the Régie intermunicipale du canal de Soulanges is to manage the development of tourism as part of the reopening of the canal.
