Year 317 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Brutus and Barbula (or, less frequently, year 437 Ab urbe condita). The denomination 317 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.
