Year 382 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Crassus, Mugillanus, Cornelius, Fidenas, Camerinus and Mamercinus (or, less frequently, year 372 Ab urbe condita). The denomination 382 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.
