FUJIWARA no Kiyofusa (year of birth and death unknown) was kuge (court noble) and retainer of the Imperial Court who lived from the end of the Heian Period to the early Kamakura Period. His father was FUJIWARA no Morinori from the Kajuji line of the Northern House of the Fujiwara clan of which FUJIWARA no Fusasaki was an ansestor. Kiyofusa KAJUJI. He was Shogoinoge (Senior Fifth Rank, Lower Grade), Kurodo (Chamberlain) and Dewa no kuni no kami (Governor of Dewa Province).

His father, Morinori, and his uncle, FUJIWARA no Tsunenori, were exiled after the Hogen War and the family declined. Kiyofusa served the Emperor Gotoba whom MINAMOTO no Zaishi, his cousin, married and made an effort to recover the luck of the family. However, when the Retired Emperor Gotoba was exiled to Oki Province as a result of the Jokyu War in 1221, Kiyofusa entered into the priesthood, going to Oki to follow him.
