Year 113 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Caprarius and Carbo (or, less frequently, year 641 Ab urbe condita) and the Fourth Year of Yuanding. The denomination 113 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.
