AD 140

"140 (year)" redirects here. For the year of the pre-Julian Roman calendar, see 140 BC.

Year 140 (CXL) was a leap year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Hadrianus and Caesar (or, less frequently, year 893 Ab urbe condita). The denomination 140 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.
