The 1554 siege of Matsuo was one of many sieges undertaken by the daimyo Takeda Shingen in his campaign to conquer Japan's Shinano province. This took place during Japan's Sengoku period, in which feudal lords (daimyo) vied for control of fiefdoms across the country.

Matsuo castle, in the Ina valley, was controlled by Ogasawara Nobusada; after his defeat, Shingen went on to seize nearby Yoshioka castle as well.
