AD 87 (LXXXVII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Saturninus (or, less frequently, year 840 Ab urbe condita). The denomination AD 87 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.
