Matsumoto Domain (松本藩, Matsumoto han^?) was a feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in Shinano Province, Honshū. The domain was centered at Matsumoto Castle, located in what is the city of Matsumoto in Nagano Prefecture.

During the Sengoku period, Matsumoto was the seat of the Ogasawara clan, the shugo of Shinano Province. However, Ogasawara clan was defeated by Takeda Shingen in a series of battles from 1542 to 1548, and his lands became part of the Takeda clan territories. After the fall of the Takeda clan, the area became a disputed region, eventually coming under the control of Tokugawa Ieyasu, who placed Ogasawara Hidemasa in charge of Matsumoto.

When Toyotomi Hideyoshi transferred Ieyasu to the Kantō region in 1590, he placed Ieyasu’s former retainer Ishikawa Norimasa in charge of Matsumoto Domain, with assessed kokudaka of 100,000 koku. Norimasa and his son Yasunaga built much of the present-day Matsumoto Castle by 1593–94. The Ishikawa were confirmed as daimyo of Matsumoto Domain after the formation of the Tokugawa shogunate, but were dispossessed due to a political scandal in 1613 involving Ōkubo Nagamasa.
