Year 351 (CCCLI) was a common year starting on Tuesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Magnentius and Gaiso (or, less frequently, year 1104 Ab urbe condita). The denomination 351 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.
