Hosokawa Tadaoki was a Japanese samurai lord and daimyo of the late Sengoku period and early Edo period. He was the son of Hosokawa Fujitaka and Numata Jakō, and the husband of the famous Christian convert Hosokawa Gracia. For most of his life, he went by the name Nagaoka Tadaoki, which had been adopted by his father and was associated with a town in their domain. Shortly after the victory at Sekigahara, Nagaoka Tadaoki reverted to his original name, Hosokawa Tadaoki.
