Year 489 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Iullus and Rufus (or, less frequently, year 265 Ab urbe condita). The denomination 489 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.
