AD 89 (LXXXIX) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Fulvus and Atratinus (or, less frequently, year 842 Ab urbe condita). The denomination AD 89 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.
