Yonekura Satonari (米倉里矩, September 13, 1733 – April 22, 1749) was the 2nd daimyō of Mutsuura Domain in southern Musashi Province, Honshū, Japan (modern-day Kanazawa-ku, Yokohama, Kanagawa prefecture) and 5th head of the Yonekura clan.
He succeeded to the head of the Yonekura clan and as daimyō of Mutsuura Domain at the age of two, on the death of his father in 1735.
In fear that the domain would be suppressed, his retainers reported Satonari’s age to be nine years old to the shogunate inspectors.
Due to his young age, the Tokugawa shogunate appointed Yanagisawa Yoshikira, daimyō of Koriyama Domain in Yamato province to be his guardian.
He was received in a formal audience by Shōgun Tokugawa Ieshige in March 1746, but fell ill and died only a few days later.
