Katō Hiroharu, alternatively named Katō Kanji (23 December 1870 – 9 February 1939), was a Japanese naval officer during the Russo-Japanese War and World War I. The given name reading 'Kanji' was used in his later life after he became famous, perhaps just before he was promoted to rear-admiral. He served as the Chief of Navy General Staff from 22 January 1929 to 11 June 1930.
