Year 301 (CCCI) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Postumius and Nepotianus (or, less frequently, year 1054 Ab urbe condita). The denomination 301 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.
