Year 139 (CXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time it was known as the Year of the Consulship of Hadrianus and Praesens (or less frequently year 892 Ab urbe condita). The denomination 139 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.
