Poznań Główny, anglicised to Poznan Main, is the chief railway station for the city of Poznań, Poland's fifth-largest city, and capital of the Greater Poland Province.

The station is located at a junction of Warsaw–Kunowice railway, Wrocław–Poznań railway, Kluczbork–Poznań railway, Poznań–Szczecin railway and Poznań–Piła railway. The train services are operated by PKP Intercity, Polregio and Koleje Wielkopolskie.

In 2023, it served 24.9 million passengers, making it the country's second busiest railway station only behind Wrocław Główny.

PKP began planning a modernisation of the station in 2007. In 2009 it began negotiations with seven companies specialising in investments in commercial real estate. A 160 million euro investment agreement was signed with developer Trigranit Development Corporation, paving the way for the construction of an integrated transport centre including a rebuilt station, car parking and a coach station.

The station and its surrounding area is being completely rebuilt and connected to the bus station and the international congress/convention centre. The entire investment aimed to provide an integrated transport complex for UEFA Euro 2012 in Poznań. Construction of the new station began in the first half of 2011 and the first phase, a fully operational booking hall and waiting area, was inaugurated by President Bronisław Komorowski on 29 May 2012. The old booking hall still exists but is not currently in use for passengers.

An integrated transport hub and shopping centre was opened on 25 October 2013. This features 250 retail units, a coach terminal, cycle lanes and a park and ride facility.

Due to the city's 2010 budget deficit, which resulted from using public funds to build a municipal stadium, the city of Poznan announced that most of the promised investment will be significantly delayed in time, and could remain un-financed even up to 2016. Under a planned third phase, the existing station building would be redeveloped with conference, office and hotel facilities. A study by TTS trade magazine informed in 2014 that the new building was already completed.

• Ignacy Jan Paderewski arrived at the Summer Station (platform 4b) on December 26, 1918, beginning a visit to Poznan which resulted in the outbreak of the Greater Poland Uprising (1918–19).
• Along the main road leading from the station to the city centre are a large number of anti-aircraft bunkers from World War II.
• During communist rule an underground hospital was prepared at the station in case of war. It was fully equipped and regularly visited by the secret services.
• Platform 4a was used twice a day by steam trains to Wolsztyn until 2014.
• On November 25, 2006 Ryszard Kapusciński unveiled a plaque in the hall of the station dedicated to Kazimierz Nowak, who travelled 40,000 km through Africa on foot and by bicycle.
• Trains are announced by computer, it is so far the only such system operated in Poland, which from 1996 to 2012 was voiced by Paweł Binkowski, a New Theatre actor. Currently, announcements are made using speech synthesis.
• Several acres of land around the railway station were the subject of a dispute between the railway authorities, the city and the authorities of the Greater Polish Voivideship since the 1990s. The railway authorities in Warsaw did not want to give this land to the City of Poznań, despite not using it. After long negotiations, the Integrated Transportation Centre (Pol. "Zintegrowane Centrum Komunikacyjne") is being built on it.
