# 351 BC

Year 351 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Peticus and Crispinus (or, less frequently, year 403 Ab urbe condita). The denomination 351 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.
