Year 109 (CIX) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Palma and Tullus (or, less frequently, year 862 Ab urbe condita). The denomination 109 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.
