The Stevenston Canal was a waterway in North Ayrshire, Scotland, built for Robert Reid Cunningham of Seabank (now Auchenharvie) and Patrick Warner of the Ardeer Estate, which ran to the port of Saltcoats from Ardeer, and Stevenston with a number of short branches to coal pits along the length of the cut. The canal opened on September 19, 1772, the first commercial canal in Scotland.
