__NOTOC__
Year '''145 BC''' was a year of the [[Roman calendar|pre-Julian Roman calendar]]. At the time it was known as the '''Year of the Consulship of Aemilianus and Mancinus''' (or, less frequently, '''year 609 ''[[Ab urbe condita]]'''''). The denomination 145 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.
