Year 173 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Albinus and Laenas (or, less frequently, year 581 Ab urbe condita). The denomination 173 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.
