Matsudaira Nobutsuna (松平 信綱, December 19, 1596 – May 4, 1662) was a Japanese daimyō of the early Edo period, who ruled the Kawagoe Domain. First serving Tokugawa Iemitsu as a page, Nobutsuna was renowned for his sagacity. He was named a rōjū in 1633. Nobutsuna led the shogunal forces to their final victory over the rebellion at Shimabara. His court title was Izu no Kami, which was the origin of his nickname, "Izu the Wise" (知恵伊豆, Chie Izu).
