Fujiwara no Yoshifusa (藤原良房, 804 - 872) was the first of the great regents from the Fujiwara clan.
A skilful politician, he managed to set up his own grandson as the emperor Seiwa, with himself acting as regent and de facto ruler. He was the first regent in Japanese history who was not himself of imperial rank.
