Year 302 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Denter and Paullus (or, less frequently, year 452 Ab urbe condita). The denomination 302 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.
