Kunishi Shinano (国司 信濃, July 22, 1842 – December 9, 1864) was a Japanese samurai in the service of the daimyō Mōri Takachika of Chōshū as a senior retainer.
Second son of Chōshū retainer Takasu Mototada, he was adopted by the heirless Kunishi Michinori (5600 koku stipend).
But in August, because of political issues, Chōshū was driven out of Kyoto, and at the same time, he was promoted to the status of senior retainer.
The First Anti-Chōshū Expedition soon followed, led by Tokugawa Yoshikatsu of the Owari domain and Saigō Takamori of Satsuma.
Eventually, with the Shogunate forcing Chōshū to submit, three men were chosen to take responsibility for the domain's actions: Masuda, Kunishi, and Fukuhara; all three men committed suicide, with Kunishi Shinano's being at Chōsenji Temple, ending his life at the young age of 22.
