Year 391 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Flavus, Medullinus, Camerinus, Fusus, Mamercinus and Mamercinus (or, less frequently, year 363 Ab urbe condita). The denomination 391 BC 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.
