Year 489 (CDLXXXIX) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Probinus and Eusebius (or, less frequently, year 1242 Ab urbe condita). The denomination 489 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.
