The Mausoleum of Galla Placidia is a Late Antique Roman building in Ravenna, Italy, built between 425 and 450. It was added to the World Heritage List together with seven other structures in Ravenna in 1996. Despite its common name, the empress Galla Placidia was not buried in the building, a misconception dating from the thirteenth century; she died in Rome and was buried there, probably alongside Honorius in the Mausoleum of Honorius at Old Saint Peter's Basilica.

Ravenna is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire during the 5th century until its collapse in 476, after which it served as the capital of the Ostrogothic Kingdom and then the Byzantine Exarchate of Ravenna.
