Kono Kazutoyo (-) was the daimyo of the Japanese Kono samurai clan during the Gempei Wars. He was loyal to the Kamakura Minamoto due to his blood relation with them, but betrayed them in the Kenkyu War of 1190. He was one of the many Minamoto vassals that sided with Emperor Go-Toba in a coalition against Minamoto Yoritomo's rising power.
