111 BC

Year 111 BC was a year of the pre-Julian Roman calendar.

At the time it was known as the Year of the Consulship of Serapio and Bestia (or, less frequently, year 643 Ab urbe condita) and the Sixth Year of Yuanding.

The denomination 111 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.
