The Battle of Kōshū-Katsunuma (甲州勝沼の戦い, Kōshū-Katsunuma no tatakai^?) was a battle between pro-Imperial and Tokugawa shogunate forces during the Boshin War in Japan. The battle followed the Battle of Toba–Fushimi on 29 March 1868 (Gregorian calendar).

After defeating the forces of the Tokugawa shogunate at the Battle of Toba-Fushimi, the Imperial forces (consisting of the feudal armies of Chōshū, Satsuma and Tosa domains) split into three columns, which progressed northeast towards the Tokugawa capital of Edo up each of the three main highways: Tōkaidō (road), Nakasendō and Hokurikudō.

Meanwhile, Kondō Isami, leader of the Shinsengumi, withdrew to Edo after the Battle of Toba-Fushimi. Once back in Edo, he met with Shogunal military commander Katsu Kaishū. Kondō created a new unit based on the surviving remnants of the Shinsengumi, called the Kōyō- chimbutai (甲陽鎮撫隊), and they departed Edo on 1 March.
