Year 383 (CCCLXXXIII) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Merobaudes and Saturninus (or, less frequently, year 1136 Ab urbe condita). The denomination 383 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.
