Baron Ishimoto Shinroku (石本 新六, 20 January 1854 – 2 April 1912) was a general in the Imperial Japanese Army, and Minister of War under the second Saionji Kinmochi administration from 1911 to 1912.

Soon after his birth, his family's house in Edo was destroyed in the Ansei earthquake of 1854, and in the subsequent Meiji Restoration, his father lost his employment and privileged status.

Afterwards, from 1879–1882, he was sent as a military attaché to France, where he was able to complete his education in engineering and artillery at the French Army's École spéciale militaire de Saint-Cyr.

His knowledge and ability caught the eye of General Terauchi Masatake, who made him a chief of staff during the Russo-Japanese War.

They had several children; their second and fifth sons also rose to the rank of general in the Imperial Japanese Army, and were killed in World War II.
