Mizuochi Chūjirō (水落忠次郎; fl. c. 1868 - 1911) was a publisher of the Meiji era based in Kyōbashi, Tokyo. His works were quite few in number and spread out chronologically, but mostly date from the late 1880s and early 1890s, including at least two printings of Ichikawa Raijirō's impressive world map (新訂萬國地圖) and maps of Japan by Kanō Morifushi (狩野守節) and Miyawaki Tsūkaku (宮脇通赫).
