Emperor Annei (安寧天皇) was the third imperial ruler of Japan to appear on the traditional list of emperors. No firm date can be assigned to this emperor and he is regarded by historians as a "legendary emperor". He was the second one of eight emperors without legend. In Kojiki and Nihonshoki only his name and geneology were recorded. The Japanese traditionally accepted his historical existence, and a tomb was attributed to him, but contemporary studies support the view that no such person existed.
His posthumous name literally means "steady tranquility."
