Hosokawa Tadatoshi (細川 忠利, December 21, 1586 – April 26, 1641) was a Japanese samurai daimyo of the early Edo period. He was the head of Kumamoto Domain. He was a patron of the martial artist Miyamoto Musashi.

He married Chiyohime (1597-1649) daughter of Ogasawara Hidemasa and adopted daughter of the second shogun, Tokugawa Hidetada.
Having studied the Yagyū Shinkage-ryū under Ujii Yashiro, Tadatoshi wanted his guest, Musashi, to fight against the sword master of his fief, and see which style was the strongest. But Ujii, despite his full license in Yagyu Shinkage style, could not strike a single blow against him after numerous bout. Lord Tadatoshi took over, but he too was powerless against Musashi. He said then about Musashi: "I never imagined there could be such a difference in levels of accomplishment!"
Tadatoshi's grave is in Kumamoto. His grandfather was Hosokawa Fujitaka.
