Year 104 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Marius and Fimbria (or, less frequently, year 650 Ab urbe condita) and the First Year of Taichu. The denomination 104 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.
