Year 163 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Gracchus and Thalna (or, less frequently, year 591 Ab urbe condita) and the First Year of Houyuan (後元). The denomination 163 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.
