Year 148 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Magnus and Caesoninus (or, less frequently, year 606 Ab urbe condita). The denomination 148 BC 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.
