AD 50 (L) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time it was known in Europe as the Year of the Consulship of Vetus and Nerullinus (or, less frequently, year 803 Ab urbe condita). The denomination AD 50 for this year has been used since the Early Middle Ages, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
