AD 9 (IX) was a common year starting on Tuesday of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Sabinus and Camerinus (or, less frequently, 762 Ab urbe condita). The denomination "AD 9" for this year has been used since the late medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
