The Galleria Nazionale d'Arte Antica (GNAA), or National Gallery of Ancient Art, is an art gallery in Rome, Italy, located on two sites: the Palazzo Barberini and the Palazzo Corsini.

The Palazzo Barberini was designed for Pope Urban VIII, a member of the Barberini family, by 16th century Italian architect Carlo Maderno on the old location of Villa Sforza. Its central salon ceiling was decorated by Pietro da Cortona with the visual panegyric of the Allegory of Divine Providence and Barberini Power to glorify the papal Barberini family.

The Palazzo Corsini, formerly known as Palazzo Riario, is a 15th-century palace that was rebuilt in the 18th century by architect Ferdinando Fuga for Cardinal Neri Maria Corsini. For a partial list of artworks, see Palazzo Corsini entry.
