Bonn-Bad Godesberg station is on the Left Rhine line (German: Linke Rheinstrecke) in the Bonn district of Bad Godesberg in the German state of North Rhine-Westphalia.

It is a four-track through station, which does not have a “home” platform attached to the station building. Instead, it has two through and overtaking tracks on two island platforms, with one platform numbered 1 and 4 and the other 2 and 3, which is unusual in Germany, but occurs several times on the Left Rhine line.

The station was inaugurated on 15 October 1855 as part of the extension of the Left Rhine line from Bonn to Rolandseck station. The need for Godesberg station, which was then in open fields, was said to stem from the fact that Godesberg was the location of the summer homes of many shareholders of the Bonn–Cologne Railway Company and the president of the Rhenish Railway Company. For years the shareholders had a table in the station buffet and insisted on almost all trains stopping in Godesberg.

From the turn of the century Godesberg grew rapidly and established itself as a resort and retirement home for retired Prussians, increasing the importance of the station. The old neoclassical entrance hall was too small and in 1908 it was replaced by the Art Nouveau building that still exists, with even its interior largely preserved; this is located just south of the old station. At the same time, the route of the railway line was raised by about a metre and subways were built under the line for the streets of Friedrichallee, Rheinallee and Bürgerstraße. As Godesberg's name was changed to Bad Godesberg in 1925, the name of the station was also similarly changed. After the city was incorporated was to Bonn in 1969, the station was again renamed in the summer 1971 timetable and received its present name of Bonn-Bad Godesberg. Since the mid-1980s express trains have not served Bonn-Bad Godesberg, except for a period in the early 1990s, when at first InterCity Night services stopped at Bad Godesberg and later Intercity-Express trains on the Bonn–Berlin route started and ended in Bad Godesberg.

Platform track 1 is served by regular regional trains to the south (Koblenz and on to Mainz). Track 2 is used by regional trains to the north (Bonn and on to Cologne). Tracks 3 and 4 are only used as sidings and as passing tracks.

Today the station is served by Regional-Express and Regionalbahn services and is served by four routes each hour, so that to and from Bonn Hauptbahnhof there are services at approximately 15-minute intervals. The station is above a Deutsche Bahn ticket office and some small shops. The main station building is now occupied by the Klangstation, a concert, theatre and lecture hall.

• Regional services RE 5 Rhein-Express Emmerich - Oberhausen - Duisburg - Düsseldorf - Cologne - Bonn - Andernach - Koblenz
