Year 397 was a common year starting on Thursday of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Caesarius and Atticus. The denomination 397 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

- Revolt of Alaric I: Stilicho traps the Visigoths under King Alaric in the Peloponnese, but decides to abandon the campaign against the Visigoths in Greece, thus allowing King Alaric to escape north to Epirus with his loot. Presumably, Stilicho has left Greece in order to prepare for military action in northern Africa, where a rebellion seems imminent.
- Emperor Honorius passes a law making barbarian styles of dress illegal in the city of Rome. As a result of this law, everybody in Rome is forbidden from wearing boots, trousers, animal skins, and long hair.
