Fujiwara no Fuhito (藤原 不比等: 659 – 13 September 720) was a powerful member of the imperial court of Japan during the Asuka and Nara periods. Second son of Fujiwara no Kamatari (or, according to one theory, of Emperor Tenji), he had sons by two women, and those sons were the founders of the four principal lineages of the Fujiwara clan: the South, North, Ceremonial, and Capital lineages. Also, he had four daughters by two other women, three by Kamohime, one by Tachibana no Michiyo. One daughter by Kamohime became Emperor Monmu's wife Miyako, who in turn gave birth to Emperor Shōmu. The daughter by Michiyo became the empress of his grandson Shōmu, Empress Kōmyō.
During the reign of Emperor Monmu, the government ordered that only the descendants of Fuhito could bear the Fujiwara surname and could be appointed in the Office of Dajokan, the center of administratives.
Fuhito was 13 years old when the Jinshin incident occurred. His father Kamatari had been a strong supporter of Emperor Tenji, but Kamatari had already died and Fuhito was too young to be appointed a governmental officer, so he was not involved in this political conflict. In 688 he appeared first as a courtier.
In 697 Prince Karu, the son of Prince Kusakabe and therefore grandson of Emperor Tenmu and Empress Jitō, was appointed crown prince. Fuhito supported this appointment strongly and gained the favor of Empress Jitō. After that, his position in the court rose steadily. In 701 Prince Obito, later the emperor Shōmu was born by Miyako. Fuhito succeeded in persuading the court to appoint Obito the crown prince, and made his other daughter a wife of Obito. Until then only a royal lady could be promoted to the empress, but he succeeded in gaining his daughter the position of empress of Obito by the emperor Shōmu. It was the first empress who did not derive from the imperial household.
He moved Yamashina-dera, the Buddhist temple which was the main temple his clan supported, to Nara and renamed it Kōfuku-ji.
