Mannheim Harbour, named Rhein-Neckar-Hafen Mannheim, is a river port on the Rhine in Mannheim, at the confluence of the Rhine and the Neckar in Baden-Wurttemberg. It consists out of 4 main harbour areas Handelshafen, Rheinauhafen, Altrheinhafen and Industriehafen, which are divided into 14 single harbour basins and 3 river docks.

It is one of the most important inland ports in Europe. The port covers 3.42 km² of water (2.83 km² Rhine, 0.59 km² Neckar) and 8.635 km² of dockland. The total land area covered from the harbour is about 11.31 km², making it the biggest inland port in Germany based on this measure.

The Rhein-Neckar-Hafen Mannheim reflects a trimodal transport node at the junction of road and rail inks and two national waterways and offers various transhipment facilities. The 4 main harbour areas have overnight rail connections to all German and many important European commercial centres and it can be accessed by road via several main motorways.
