Year 374 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Second year without Tribunate or Consulship (or, less frequently, year 380 Ab urbe condita). The denomination 374 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.
