Year 455 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Vaticanus and Cicurinus (or, less frequently, year 299 Ab urbe condita). The denomination 455 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.
