was the fourth ruler of Northern Fujiwara in Mutsu Province, Japan, the second son of Hidehira. Against his father's will, he first hid Yoshitsune in escape but later killed him, fearing the possibility of Yoritomo's intervention. In 1189 he was defeated by Yoritomo's forces and was subsequently beheaded, an event that marked the end of the Northern Fujiwara. A casket purportedly containing the head of Fujiwara no Yasuhira is housed within the Konjiki-dō at Chūson-ji in Iwate Prefecture.
