Palazzo Barberini is a palace in Rome, facing the Piazza Barberini in Rione Trevi. It houses the Galleria Nazionale d'Arte Antica.

Today, Palazzo Barberini houses the Galleria Nazionale d'Arte Antica, one of the most important painting collections in Italy. It includes Raphael's portrait La fornarina, Caravaggio's Judith Beheading Holofernes and a Hans Holbein portrait of Henry VIII.

The palace also houses the Italian Institute of Numismatics.

The European Convention on Human Rights (ECHR), which created the European Court of Human Rights, was signed here on 4 November 1950, a milestone in the protection of human rights.

Hidden in the cellars of the rear part of the building, a Mithraeum was recently[when?] found, dating probably from the second century AD.
