The Stecknitz Canal () was an artificial waterway in northern Germany which connected Lauenburg and Lübeck on the Old Salt Route by linking the tiny rivers Stecknitz (a tributary of the Trave) and Delvenau (a tributary of the Elbe), thus establishing an inland water route across the drainage divide from the North Sea to the Baltic Sea. Built between 1391 and 1398, the Stecknitz Canal was the first European summit-level canal and one of the earliest artificial waterways in Europe. In the 1890s the canal was replaced by an enlarged and straightened waterway called the Elbe–Lübeck Canal, which includes some of the Stecknitz Canal's watercourse.
