Roma Porta San Paolo is the terminal train station of the Rome–Lido railway line in Rome (Italy).

The building of the station was started, together with the one of the railway, at the beginning of 1919, after the inauguration ceremony of December 30, 1918 in the presence of King Victor Emmanuel III.

A quite similar one was the Ostia Nuova terminal train station, whose foundation stone was laid on December 10, 1920, also in the presence of the King, and that was destroyed during the war.

The graffiti decorating the interior of the station are works by the Florentine artist Giulio Rosso.

The station and the railway line were inaugurated on August 10, 1924, with a special ride, in which Mussolini – who had become Prime Minister in the meanwhile – took part.
