Year 58 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Piso and Gabinius (or, less frequently, year 696 Ab urbe condita). The denomination 58 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.
