Baron Misu Sōtarō (三須 宗太郎, 16 September 1855 – 24 December 1921) was an admiral in the early Imperial Japanese Navy.

His father, Misu Kumajirō, was a retainer of the Ii clan, and was assigned command of the defenses of Edo Bay against the incursions of foreign vessels.

In September 1893, he was reassigned to serve in the Imperial Japanese Navy General Staff as head of the Naval Personnel Bureau.

He was in charge of payroll, awards and promotions, burial of fallen sailors, compensation to families, etc., and served in this desk job throughout the First Sino-Japanese War.

[3] In 1901, he was promoted to rear admiral and recalled as head of the Naval Personnel Bureau in the Navy General Staff.

During the personnel reorganization within the navy prior to the war, Naval Minister Yamamoto Gonnohyōe was convinced that victory could not be obtained unless Admiral Hidaka Sonojo was replaced by Tōgō Heihachirō.
