The Battle of Ueno (上野戦争, Ueno Sensō^?) was a battle of the Boshin War, which occurred on July 4, 1868 (Meiji 1, 15th day of the 5th month), between the troops of the Shōgitai under Shibusawa Seiichirō and Amano Hachirō, and Imperial "Kangun" troops.

Though the Shōgitai was mostly made up of former Tokugawa retainers and residents of the surrounding provinces, some domains supported the Shōgitai, such as Takada han (Echigo Province, 150,000 koku), Obama han (Wakasa Province, 103,000 koku), Takasaki han (Kōzuke Province, 52,000 koku), and Yūki han (Shimosa Province, 18,000 koku).

Facing them were the combined forces of the Chōshū, Ōmura, Sadowara, Hizen, Chikugo, Owari, Bizen, Tsu, Inaba, and Higo domains, under the general command of Chōshū's Ōmura Masujirō.

Shibusawa and Amano initially had the 2000-strong Shōgitai posted in Ueno to protect Tokugawa Yoshinobu, who was, at the time, in self-imposed confinement at Ueno's Kan'ei-ji Temple, as well as Prince Rinnōji no Miya Yoshihisa, who was the abbot of the temple, and was to become the new dynastic leader of the Tokugawa resistance as "Emperor Tōbu".
