Year 143 (CXLIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Torquatus and Hipparchus (or, less frequently, year 896 Ab urbe condita). The denomination 143 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.
