The Maidan Konstytutsii is a station on Kharkiv Metro's Kholodnohirsko–Zavodska Line. The station was opened on 23 August 1975. It is located in the historical part of Kharkiv, beneath the Maidan Konstytutsii, previously known as Soviet Square.
The Maidan Konstytutsii station forms a complex with the adjacent station, Istorychnyi Muzei, on the Saltivska Line. Before the Istorychniy Muzei station's completion in 1984, a relief marble architectural item adorned with the hammer and sickle was located on the station. Inside the passenger transfer tunnel is the Kharkiv Metro's only public restroom, which is unlike the western European metro systems.
