The Rheinkniebrücke (English: Rhine knee bridge) is a cable-stayed bridge leading over the Rhine at the Rheinknie in Düsseldorf with a six-lane motor road and two combined pedestrian and cycle paths, which was opened to traffic on 16 October 1969.

The architect Friedrich Tamms was entrusted with the development of the project.

The bridge was built in 1965 by Deutsche Maschinenbau-Aktiengesellschaft (Demag AG), Gutehoffnungshütte, Aktienverein für Bergbau und Hüttenbetrieb and Hein, Lehmann & Co..

At the time of its opening, it was a cable-stayed bridge with the longest span in the world.
