text: # 125 BC
  
  Year 125 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Hypsaeus and Flaccus (or, less frequently, year 629 Ab urbe condita) and the Fourth Year of Yuanshuo. The denomination 125 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.
