Year 201 (CCI) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Fabianus and Arrius (or, less frequently, year 954 Ab urbe condita). The denomination 201 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.
