Year 60 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Metellus Celer and Afranius (or, less frequently, year 694 Ab urbe condita). The denomination 60 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.
