Abe no Yoritoki (安倍頼時)(d. 1057) was the head of the Abe clan of samurai whose behavior triggered the events known as the Zenkunen War (Early Nine Years' War) of Japan's Heian period. As the bearer of the title of chinjufu shogun (Defender of the North), Abe was responsible for overseeing the subjugation of the aboriginal inhabitants of Honshū's northernmost areas, and the protection of Japanese communities from them.
