Year 381 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Camillus, Albinus, Albinus, Medullinus, Flavus and Ambustus (or, less frequently, year 373 Ab urbe condita). The denomination 381 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.
