St. Petersburg–Glavny (Russian: Санкт-Петербург-Главный), is a railway station terminal in Saint Petersburg, Russia.

It is a terminus for the Saint Petersburg–Moscow Railway and other lines running from Central and South Russia, Crimea, Siberia and Eastern Ukraine.

The oldest preserved station in the city, it was erected in 1844-51 to a design by Konstantin Thon.

[1] As Nicholas I of Russia was the reigning monarch and the greatest patron of railway construction in the realm, the station was named Nicholaevsky after him.

Although large "Venetian" windows, two floors of Corinthian columns and a two-storey clocktower at the centre explicitly reference Italian Renaissance architecture, the building incorporates other features from a variety of periods and countries.
