Year 267 (CCLXVII) was a common year starting on Tuesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Paternus and Arcesilaus (or, less frequently, year 1020 Ab urbe condita). The denomination 267 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.

• First Gothic invasion: The Goths, originally from Scandinavia, with the Sarmatians (from modern Iran), invade the Balkans and Greece. They ravage Moesia and Thrace.

After the Sack of Athens, an Athenian militia force (2,000 men), under the historian Dexippus, pushes the invaders to the north where they are intercepted by the Roman army under emperor Gallienus. He wins an important victory near the Nestos River, on the boundary between Macedonia and Thrace.
