Year 221 BC was a year of the pre-Julian Roman calendar. At the time it was known in Rome as the Year of the Consulship of Asina and Rufus/Lepidus (or, less frequently, year 533 Ab urbe condita). The denomination 221 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.
