Makino Tadayuki (牧野 忠恭, October 22, 1824 – September 1, 1878) was a Japanese daimyo of the late Edo period.
The Makino were identified as one of the fudai or insider daimyō clans which were hereditary vassels or allies of the Tokugawa clan, in contrast with the tozama or outsider clans.
The fudai Makino clan originated in 16th century Mikawa Province. Their elevation in status by Toyotomi Hideyoshi dates from 1588. They claim descent from Takechiuchi no Sukune, who was a legendary Statesman and lover of the legendary Empress Jingū.
Tadayuki was part of the senior branch of the Makino which was established at Tako Domain in Kōzuke Province in 1590; and in 1616, their holdings were moved to Nagamine Domain in Echigo Province. From 1618 through 1868, this branch of the Makino remained at Nagaoka Domain (74,000 koku) in Echigo Province.
Tadayuki was the 11th-generation head of this senior line of the Makino.
The head of this clan line was ennobled as a "Viscount" in the Meiji period.
Tadayuki served in the Tokugawa shogunate as a rōjū. He was the shogunates's fifty-fifth Kyoto shoshidai in the period spanning September 17, 1862 through July 26, 1863.
During the Boshin War of 1868–1869, the forces from Nagaoka Han fought against Meiji government forces. In this period, Tsuginosuke Kawai (1827–1868), was the military general of the Makino Clan; and today the Tsuginosuke Kawai Memorial Hall is sited in Naga-chô where Kawai’s residence once stood. When Meiji forces took Nagaoka, Kawai withdrew towards Aizu and Sendai along with Makino Tadayuki and other fleeing clan leaders.
Tadayuki died in Tokyo in 1878, and is buried at Saikai-ji Temple.
