Year 477 (CDLXXVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year after the Consulship of Basiliscus and Armatus (or, less frequently, year 1230 Ab urbe condita). The denomination 477 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.
- January 25 – King Genseric dies a natural death at Carthage and is succeeded by his eldest son Huneric. He maintains control with his Vandal fleet over the islands in the western Mediterranean Sea and lifts the policy of his father of persecuting the Roman Catholics in Africa.

The Britons engage him upon landing but his superior force besieges them at Pevensey and drives them into the Weald. Over the next nine years, Saxon coastal holdings are gradually expanded.

Yang Xuanzhi, in the Record of the Buddhist Monasteries of Luoyang (547), and Li Xian, in the Ming Yitongzhi (1461), concur with Daoxuan's location and attribution. For alternate founding date, see 497).
