Prince Tokugawa Yoshinobu was the 15th and last shōgun of the Tokugawa shogunate of Japan. He was part of a movement which aimed to reform the aging shogunate, but was ultimately unsuccessful.

Immediately upon Yoshinobu's ascension as shōgun, major changes were initiated. A massive government overhaul was undertaken to initiate reforms that would strengthen the Tokugawa government. In particular, assistance from the Second French Empire was organized, with the construction of the Yokosuka arsenal under Léonce Verny, and the dispatch of a French military mission to modernize the armies of the bakufu. The national army and navy, which had already been formed under Tokugawa command, were strengthened by the assistance of the Russians, and the Tracey Mission provided by the British Royal Navy. Equipment was also purchased from the United States. The outlook among many was that the Tokugawa Shogunate was gaining ground towards renewed strength and power; however, it fell in less than a year.

After resigning in late 1867, he went into retirement, and largely avoided the public eye for the rest of his life.
