Marquess Hachisuka Mochiaki (蜂須賀 茂韶, 28 September 1846 – 10 February 1918) was the 14th and final daimyō of Tokushima Domain, Awa Province, and the 2nd President of the House of Peers in Meiji period Japan.

Quick to see the direction in which the wind was blowing, he pledged loyalty to the Imperial forces, and led his troops against Tokugawa partisans in Mutsu Province.

His forces were armed with western rifles and accompanied by British military advisors, giving him a much greater strength than their small numbers might have indicated.

In 1882, Hachisuka was envoy extraordinary and minister plenipotentiary to France, and received the title of kōshaku (marquis) under the new kazoku peerage system.

Translated from the corresponding article in the Japanese Wikipedia Hachisuka Mochiaki ran an experimental farm in Hokkaidō, as he often stated that the nobility needed to have some gainful employment other than government service.
