The Hohenzollern Bridge (German: Hohenzollernbrücke) is a bridge crossing the river Rhine in the German city of Cologne (German Köln). It crosses the Rhine at kilometre 688.5. Originally, the bridge was both a railway and street bridge, however, after its destruction in 1945 and its subsequent reconstruction, it was only accessible to rail and pedestrian traffic.

It is the most heavily used railway bridge in Germany with more than 1200 trains daily, connecting the Köln Hauptbahnhof and Köln Messe/Deutz stations.

The bridge was constructed between 1907 and 1911 after the old bridge, the Cathedral Bridge (Dombrücke), was demolished. The Cathedral Bridge was unable to handle the increasing traffic in Cologne. The new bridge was named after the House of Hohenzollern.

The President of the Railway Directorate Cologne, Paul von Breitenbach started planning the construction and handed over this work to his successor Rudolf Schmidt in 1906. The project was headed by the railway engineer Fritz Beer and under his direction the designs were worked out by Friedrich Dirksen. The construction of the Hohenzollern bridge took place from 1907 to 1911. Inauguration took place on May 22, 1911 by Kaiser Wilhelm II.

The bridge consisted of three adjacent bridge parts, each with three iron truss arches (passage openings) in the longitudinal direction to accommodate four railroad tracks and a road. Although the location of the bridge and the railway station were already controversial in previous structures, the Hohenzollern bridge took over the orientation of the previous bridge on the central axis of the cathedral.

Four equestrian statues of Prussian kings and German emperors of the Hohenzollern family flank each ramp. The Cathedral Bridge was already adorned with the statues of Friedrich Wilhelm IV of Prussia by sculptor Gustav Blaeser and Kaiser Wilhelm I by Friedrich Drake, which are now placed on the right bank of the Rhine (see pictures above). In addition sculptor Louis Tuaillon made the equestrian statues of Emperor Friedrich III and, during his lifetime, Wilhelm II, which were placed on the left bank of the Rhine (see pictures below). They depict the era of Prussian rule in the Rhine province.
