Taira no Sadayoshi (平 貞義) was a governor of Higo and Chikugo provinces in Kyūshū, and a samurai commander for the Taira clan during the Genpei War of the 1180s. Following the war, his life was spared as a result of an intercession by Utsunomiya Tomotsuna. He thus spent his retirement as a Buddhist monk, going by the appellation Higo-Nyūdo. His father was Taira no Iesada.
