Room 12 contains Late Hellenistic and Roman objects, including a famous statue of Antinous.

The main exhibit of the statue of Antinous, protégé of the emperor Hadrian; it is probably one of the best specimens of the depictions of the young man which were erected all over the Roman Empire after his untimely death under order of the emperor.
Close to Antinous stands a head of a man probably depicting Titus Quinctius Flamininus, the Roman general who conquered Delphi in 198 BC.
 In the middle of the room stands a round altar made of Pentelic marble and coming from the Sanctuary of Athena Pronaia.
It is decorated in three bands with cyma recta and astragalus patterns and twelve female figures.
It dates to the 2nd century BC.
Another important exhibit is the pedestal with the frieze in relief constituting the Monument of Aemilius Paullus.

Along the south side of the room are displayed parts of the Roman frieze decorating the theatre.
They consist of depictions of scenes from the life and deeds of Hercules, such as the garden of the Hesperids, Cerberus, the lion of Nemea, a Centaur, Antaeus, the belt of Hippolyte, the horses of Diomedes etc.
