Year 367 (CCCLXVII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lupicinus and Iovanus (or, less frequently, year 1120 Ab urbe condita). The denomination 367 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.
