Rokkaku Hisayori served as a bushō and shugo daimyō during the late-Muromachi period. He was the eleventh head of the Rokkaku clan serving as the military governor of Ōmi Province.
Hisayori was born as the third son of Rokkaku Mitsutsuna, a bushō and shugo daimyō and the ninth head of the Rokkaku clan. He originally entered the priesthood at the Shōkoku Temple in Kyōto, in 1445, his second eldest brother, Rokkaku Tokitsuna, became a leader of the kokujin, or provincial landowners, in Ōmi, in opposition to his father and eldest brother, Rokkaku Mochitsuna. After suffering a defeat, his father and Mochitsuna took their own lives. As a result, upon orders of the Muromachi bakufu, he returned to secular life and adopted the name of Hisayori. In 1446, he eliminated his second eldest brother and succeeded to the headship of the Rokkaku clan.
Hisayori, however, was not able to stem the decline in power of the Rokkaku clan. After enduring the intervention of Kyōgoku Mochikiyo, he died in a fit of anger on 10/2 of Kōshō 2 (1456). The headship of the clan was inherited by his son, Rokkaku Yukitaka (later known as Rokkaku Takayori). At the time, he was young so his nephew and the orphan of Tokitsuna, Rokkaku Masataka, served as his guardian.
