Year 123 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Balearicus and Flamininus (or, less frequently, year 631 Ab urbe condita) and the Sixth Year of Yuanshuo. The denomination 123 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.
