Konstanz station is the largest passenger station in the German city of Konstanz (Constance). Konstanz has the function of a border station. It is served by regional and long distance services operated by Deutsche Bahn and Swiss Federal Railways. It is the end of the Upper Rhine Railway and the beginning of the Etzwilen–Konstanz line.

Konstanz is served hourly by Regional-Express trains on the Black Forest Railway. Until the timetable change in 2015, Interregio-Express and RE trains alternated from Kreuzlingen or Konstanz to Karlsruhe. This was changed with the timetable change, so that there is now a continuous RE hourly to Karlsruhe.
