Year 372 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Fourth year without Tribunate or Consulship (or, less frequently, year 382 Ab urbe condita). The denomination 372 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.
