What Is the Longest River in Germany?

The longest river in Germany is the Rhine, which flows for 537 miles within the country. Although the majority of academic sources and reference materials list the total length of the Rhine as 820 miles, it only extends for around 765 miles from its two sources to the river’s delta, according to a biologist at the University of Cologne who discovered the error in 2010.

The second longest river in Germany is the Elbe, which runs for 435 miles, followed by the Danube, which flows for 402 miles. Other major rivers in the country include the Ems, Isr, Lech, Moselle, Oder, Weser and Spree.
