Okutono Domain (奥殿藩, Okutono-han), also known as Okudono,[1] was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Kamo District and Nukata Districts of Mikawa Province (part of modern Aichi Prefecture), and in Saku District, Shinano Province, (part of modern Nagano Prefecture) Japan.

Matsudaira Masatsugu was awarded a 6000 koku hatamoto post within the Tokugawa shogunate for his services in the Battle of Osaka.

His son, Matsudaira Noritsugu, increased to 16,000 koku, and was thus promoted to the ranks of the fudai daimyō in 1684.

However, the domain suffered greatly due to inclement weather and flooding of the Yasaku River during the Kyōhō period, which led to crop failure and famine.

[2] In the Bakumatsu period, the domain achieved prominence thanks to its last daimyō, Matsudaira Norikata, who served as a senior councilor in the final years of the Tokugawa shogunate.
