Railway station in Istanbul, Turkey

Haydarpaşa station (Haydarpaşa Garı) is a railway station in Istanbul, that was, until 2012 the main city terminal for trains travelling to and from the Anatolian side of Turkey. It used to be Turkey's busiest railway station. (Its counterpart on the European side of the city was Sirkeci station which served train services to and from the Thracian side of the country.) The station building still houses the headquarters for District 1 of the State Railways but since a fire in 2010 the station has not been in use and its future remains uncertain. Haydarpaşa stands on an embankment over the Bosphorus just south of the Port of Haydarpaşa (one of the main container terminals in Turkey) and is slightly north of busy Kadıköy. Until the rail service was suspended, ferry services connected it to Eminönü, Karaköy and Kadıköy. The closure of the station has been very controversial and a group known as the Haydarpaşa Solidarity Group (Haydarpaşa Dayanışması) has staged regular protest sit ins in front of it amid fears that the station and port would be sold; a plan involving seven skyscrapers provoked especially strong adverse reaction. In December 2015, the reintegration of Haydarpaşa station into the Marmaray network was theoretically approved along with the restoration and rehabilitation of the station building and platforms. However, in 2022 its future still remained unclear.

In 1871 Sultan Abdülaziz ordered the first railway line to be built from Haydarpaşa in Istanbul to İzmit. Haydarpaşa station opened in 1872, by which time the railway extended as far as Gebze. In 1888 the Anatolian Railway (Chemins de fer Ottomans d'Anatolie, CFOA) took over the line and the station. Since the station was built right beside the Bosphorus, freight trains could unload at Haydarpaşa and the freight could be transferred straight to ships. Haydarpaşa station saw its first regular passenger service daily train from Haydarpaşa to İzmit in 1890. World War I broke out in 1914 and the Ottoman Empire sided with the Central Powers against the Allied Powers. When the Ottomans lost İstanbul was taken over by the British Empire and Haydarpaşa fell under British military control during the occupation. In 1917 the architect Vedat Tek designed the pretty terminal decorated with Kütahya tiles where ferries used to deposit would be train passengers in front of the station.

The Turkish Independence War ended on 29 October 1923 with the British withdrawal from Istanbul and the formation of the Republic of Turkey. Haydarpaşa terminal was still under CFOA control but in 1927 the newly formed Turkish State Railways (TCDD) took over the CFOA and the terminal as part of the process of nationalising all the Turkish railways. In 1927 the CIWL started a premier train service, the all sleeper Anatolian Express, that travelled daily between Haydarpaşa and Ankara. In 1938 the Eastern Express started running from Haydarpaşa to the eastern Turkish city of Kars, a distance of The famous Taurus Express from Haydarpaşa to Baghdad, a distance of , entered service in 1940. In 1965 the Trans Asia Express began running from Haydarpaşa to Tehran, a distance of In 1969 the tracks from Haydarpaşa to Gebze were electrified with 25 kV AC catenary for the Haydarpaşa Gebze commuter line. In 2011 the World Monuments Fund, the New York based heritage preservation organisation, placed the railway terminal on its 2012 Watch, drawing attention to its uncertain future. In November 2012 the station hosted a three day art exhibition entitled Haydarpasa: Past, Present and Uncertain Future, which was organised in collaboration with the WMF, and featured Canadian and Turkish artists and photographers seeking to raise international interest in preserving the station as a transportation hub. On 2 February 2012 Haydarpaşa Station closed to long distance trains to allow for the construction of the Istanbul–Ankara high speed railway and the Marmaray which now connects Istanbul's Asian and European sides, halting train services between Istanbul and the Anatolian region of Turkey). Although work on the Marmaray has now been completed along with high speed train services to Ankara, Konya and Eskişehir, these now leave from stations other than Haydarpaşa which remained closed and under restoration in 2022.

In 2018, remains of a Byzantine coastal town were uncovered during restoration work on the station. The excavations also unearthed a Byzantine era fountain, a large fortification wall and a ceramic brick kiln. Dozens of graves were also discovered; in October 2018, archaeologists found an intact skeleton wearing a scented necklace. Jewellery and coins dating back to between 610 641 and 527 565 A. D were also found. The buildings of the Haydarpaşa Numune Hospital, GATA Military Hospital, Dr. Siyami Ersek Hospital and the present day Haydarpaşa Campus of the Marmara University designed by architects Alexander Vallaury and Raimondo D'Aronco are also near the station.
