The Duisburg tramway network (German: Straßenbahnnetz Duisburg) is a network of tramways forming part of the public transport system in Duisburg, a city in the federal state of North Rhine-Westphalia, Germany.

Opened in 1881, the network has been operated since 1940 by the Duisburger Verkehrsgesellschaft [de] (DVG) and is integrated into the Verkehrsverbund Rhein-Ruhr (VRR).

It now forms part of the larger Duisburg Stadtbahn system, which in turn makes up part of the Rhine-Ruhr Stadtbahn system.

As of 2013[update], the Duisburg tramway network had the following lines: 43 type GT10NC-DU trams are operated in Duisburg, which were built by Duewag from 1986 until 1993.

[1] The first of 47 new Bombardier Flexity trams was delivered in 2020, which are scheduled to replace the old trams.
