The Main-Danube Canal is an artificial waterway in Germany that connects the Main with the Danube. It stretches over a distance of approximately 171 kilometers and crosses the federal states of Bavaria and Baden-Württemberg. The idea for the canal arose in the 19th century, but its actual realization only took place in the late 20th century.

The canal is mainly used for shipping traffic and provides an important connection between the Rhine-Main area and the Danube region.

The construction of the canal was an engineering masterpiece as it had to overcome various rivers and height differences. Locks and canal bridges were built to complete the waterway. The Main-Danube Canal is important not only for the economy, but also for tourism, as it leads through picturesque landscapes and historically interesting cities.
