Year 380 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Poplicola, Poplicola, Maluginensis, Lanatus, Peticus, Mamercinus, Fidenas, Crassus and Mugillanus (or, less frequently, year 374 Ab urbe condita). The denomination 380 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.
