Year 161 (CLXI) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Caesar and Aurelius (or, less frequently, year 914 Ab urbe condita). The denomination 161 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.
