Year 57 BC was a year of the pre-Julian Roman calendar. Contemporaneously, in the Roman Republic, it was known as the Year of the Consulship of Lentulus and Metellus (or, less frequently, year 697 Ab urbe condita). The denomination 57 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.
