Year 115 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Scaurus and Metellus (or, less frequently, year 639 Ab urbe condita) and the Second Year of Yuanding. The denomination 115 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
