Französische Straße was a Berlin U-Bahn underground station on the line located under the street Friedrichstraße in central Berlin.
This station was built by Grenander/Fehse/Jennen and opened in 1923. In 1945 it closed for a few months; it was permanently closed in 1961. During the Cold War, the station became a ghost station. The station was closed to passenger traffic, and the underground trains of the West Berlin BVG passed the island platform in East Berlin slowly without stopping. In 1990, after the Berlin Wall fell, the station became accessible again. In 1995, the platform had to be lengthened by 25 m so that the long, six-car trains could stop there. It is the only former partition-related ghost station in Berlin to have since been closed a second time, albeit for different reasons.
