Year 79 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Isauricus and Pulcher (or, less frequently, year 675 Ab urbe condita). The denomination 79 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.
