, or , is a historical Japanese text. It was generally believed to have been one of the earliest Japanese histories until the middle of the Edo period, when scholars such as Tokugawa Mitsukuni successfully contended that it was an imitation based on the "Nihon Shoki", the "Kojiki" and the "Kogo Shūi". Scholarship on the "Kujiki" generally considers it to contain some genuine elements, specifically that Book 5 preserves traditions of the Mononobe and Owari clans, and that Book 10 preserves the earlier historical record the "Kokuzō Hongi".
