Year 321 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Calvinus and Caudinus (or, less frequently, year 433 Ab urbe condita). The denomination 321 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.
