Year 131 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Mucianus and Flaccus (or, less frequently, year 623 Ab urbe condita) and the Fourth Year of Yuanguang. The denomination 131 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.
