Romulus Augustus (; born c. AD 461 – died after AD 476, and was apparently still alive as late as 507) was an emperor (alleged usurper) reigning over the Western Roman Empire from 31 October AD 475 until 4 September AD 476. His deposition by Odoacer traditionally marks the end of the Western Roman Empire, the fall of ancient Rome, and the beginning of the Middle Ages in Western Europe.
