99 BC
# 99 BC

Year 99 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Antonius and Albinus (or, less frequently, year 655 Ab urbe condita) and the Second Year of Tianhan. The denomination 99 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.
