Year 263 (CCLXIII) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Albinus and Dexter (or, less frequently, year 1016 Ab urbe condita). The denomination 263 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
