AD 3 (III) or 3 AD was a common year starting on Monday or Tuesday (link will display the full calendar) of the Julian calendar (sources differ, see leap year error for further information) and a common year starting on Monday of the proleptic Julian calendar. In the Roman Empire, it was the Year of the Consulship of Lamia and Servilius (or, less frequently, year 756 Ab urbe condita). The denomination "AD 3" 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.

AD 3 was the only prime-numbered Year of the Pig.
