Year 263 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Mesella and Crassus (or, less frequently, year 491 Ab urbe condita). The denomination 263 BC 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.
