Zürich Wiedikon railway station (German: Bahnhof Zürich Wiedikon) is a railway station on the Zürich S-Bahn system in Wiedikon in the western part of the Swiss city of Zürich. It is the only railway station in Switzerland where the ticket office building is located on a bridge above the tracks – in German, this is known as Reiterbahnhof.

The station is served by S-Bahn trains on the Lake Zürich left bank line approaching the city from the south and south-east directions. InterCity and InterRegio trains and the accelerated S25 service bypass the station through the Zimmerberg Base Tunnel since 2003.

The first Wiedikon station opened in 1875 with the opening of the Lake Zürich left bank line. The line's original routing through the area differed from the current alignment and was largely at street level, with many level crossings, and passed immediately to the east of the existing station.

The current station was built between 1925 and 1927, when the line was rerouted to the west, using a lower level alignment with more tunneling. The architect was Hermann Herter.

The railways approach the station from both north and south are below ground level, with a cutting to the north and the 848 m (2,782 ft) Ulmberg tunnel is to the south. The connecting line to the Giesshübel station on the Sihltal Zürich Uetliberg Bahn diverges at the southern end of the station, also in tunnel. The latter is not normally used for passenger services unless trains are diverted.

The station has three tracks and three platforms. All the platforms can be used by trains in both directions on the Lake Zurich line, but only the westernmost is accessible to trains on the Giesshübel connector.

The station is served by lines S2, S8, and S24 of Zürich S-Bahn:

• S2: half-hourly service between Zürich Airport and Ziegelbrücke (via Zürich HB); on weekends trains continue from Ziegelbrücke to Unterterzen.
• S8: half-hourly service between Winterthur and Pfäffikon SZ via Zürich HB.
• S24: half-hourly service between Winterthur and Zug (via Zürich HB); continues from Winterthur alternately to Thayngen or Weinfelden.

During weekends, there is a nighttime S-Bahn service (SN8) offered by ZVV:

• SN8: hourly service between Pfäffikon ZH and Lachen via Zürich HB.
