Year 427 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Ahala and Mugillanus (or, less frequently, year 327 Ab urbe condita). The denomination 427 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.
