Ôkubo Tadahiro was a Tokugawa shogunate official who served in several bugyô (Magistrate) positions in the Bakumatsu period.
After serving as Nagasaki bugyô for a time in 1857, he was then named kinrizuki (a shogunate official attached to the imperial court) until 1859, when he was reassigned to the position of Kyoto machi bugyô. Toward the end of the 8th month of 1859, he was dismissed from the position of Nishinomaru rusui amidst the dismissal and (in some cases) house confinement of a number of prominent officials associated with foreign affairs.
