Maki Yasuomi (真木 保臣?, April 7, 1813 – August 22, 1864) was a Japanese samurai of the late Edo period, who served as a retainer of the Arima clan of Kurume in northern Kyūshū. He was also a Shinto priest of the Suiten-gū shrine in Kurume. Maki, also known by his court title of Maki Izumi no kami (真木和泉守?) or simply Maki Izumi (真木 和泉?), was a student of the Mito school's sonnō-jōi ideology, and in particular, Aizawa Seishisai's philosophy.
Maki took part in the Kinmon Incident of 1864 and committed suicide near Osaka with his men, after being chased and surrounded by Aizu and Shinsengumi troops.
