Year 262 (CCLXII) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Gallienus and Faustianus (or, less frequently, year 1015 Ab urbe condita). The denomination 262 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.
