Baron Tanaka Giichi (Japanese: 田中 義一; IPA: [ta̠na̠ka̠ ɡʲiːt͡ɕi]; 22 June 1864 – 29 September 1929) was a Japanese general and politician who served as Prime Minister of Japan from 1927 to 1929.
Born to a samurai family in the Chōshū Domain, Tanaka became an officer in the Imperial Japanese Army and rose through the ranks. He served as Minister of the Army under Prime Ministers Hara Takashi and Yamamoto Gonnohyōe. After retiring from active duty he accepted the presidency of the Rikken Seiyūkai, a major conservative party. Following the resignation of the Wakatsuki Cabinet in 1927, Tanaka was appointed Prime Minister. In foreign affairs, he pursued a hawkish policy; in domestic affairs, he sought to suppress communist and socialist movements. Criticised for his handling of the unauthorised assassination of Zhang Zuolin by a Kwangtung Army officer, he resigned in 1929 and died soon afterwards.
