Stadtpark is a station on U4 of the Vienna U-Bahn. It is located in the Landstraße District. It opened in 1978. It is one of the few Otto Wagner buildings on the U4 that has been preserved almost in its original condition. The station, which is open-air and has two side platforma, is located in a cutting and lies parallel to the Wien Canal. Exits lead via a fixed staircase through a station building into Johannesgasse via a staircase or an elevator directly into the part of the Stadtpark located in the 3rd district. The station building hangs over the portal of the Wienfluss designed by Friedrich Ohmann, an opponent of Otto Wagner. Also in the immediate vicinity of the station are the Kursalon Hübner and the Vienna Ice Skating Club as well as the large InterContinental Vienna Hotel

The station, designed by Otto Wagner and built on behalf of the Commission for Transport Facilities in Vienna. The station was known as the "Tegetthoff Bridge" during the planning and construction phase and was structurally completed in December 1897. It finally went into operation on June 30th, 1899 as part of the Lower Vienna Vallet Line of the Vienna Steam City Railway, which ran from Meidling Hauptstraße Station to Hauptzollamt Station, today Wien Mitte Station. On December 8th, 1918, it was closed due to the coal shortage after the First World War and reopened on September 7th, 1925 as part of the new Vienna Electric City Railway. The station has been a listed building since 1934.

In 1977 and 1978, the station was adapted for underground operations. The platforms were raised by 45 centimetres and the track was lowered by 15 centimetres, which required a corresponding shift in the wall friezes and platform roofs. The U4 trains served the Stadtpark station for the first time on August 15th, 1978. The exit to the Stadtpark was only built later.

The general renovation of the station began on November 30th, 2015, and some of the platforms were closed. After completion of the work on the platforms, the station reopened on January 30th, 2017.
