Tokugawa Yoshimichi (徳川 吉通, October 29, 1689 – September 15, 1713) was daimyō of Owari Domain during early-Edo period Japan.
On August 25, 1695, he was permitted to take the Tokugawa surname in place of Matsudaira, and in December of the same year was awarded with one kanji from Shōgun Tokugawa Tsunayoshi's name, lower 4th court rank and ceremonial court title of Captain of the Left Guards.
On the death of his father in 1699, Yoshimichi officially became the 4th Tokugawa daimyō of Owari Domain with 3rd Court Rank, but since he was only age 11 at the time, his uncle Matsudaira Yoshiyuki served as regent, and he continued to reside at the Yotsuya residence of his mother in Edo until 1705.
During this period, he studied Japanese martial arts, Confucianism, and Shinto, and later was considered to be a scholarly and wise ruler of Owari Province.
However, in May 1713, a plot by some of his retainers in Nagoya resulted in twelve sentences of death or seppuku, and Yoshimichi went into permanently secluded retirement back with his mother, Hōju-in, on July 21 of the same year.
