Tokugawa Nariaki (徳川 斉昭, April 4, 1800 – September 29, 1860) was a Japanese daimyō who ruled the Mito Domain (now Ibaraki Prefecture) and contributed to the rise of nationalism and the Meiji Restoration.

[1] Nariaki was also leader of the Jōi (expel the barbarian) party and made a Bakufu adviser on national defence.

His own view was that the bakufu should strengthen its military and fight the foreigners, and was at odds with Ii Naosuke on the issue.

[3] Ōkuni and Nariaki therefore laid some foundations for the Meiji restoration as well as the development of State Shinto.

Nariaki was placed under house arrest as part of the Ansei Purge 1844[4] in favor of his son Yoshiatsu, and died of a heart attack in 1860, at age 60.
