is one of the six wards of the city of Chiba in Chiba Prefecture, Japan, and is the seat of the city government, and the location of the prefectural government offices for Chiba Prefecture. It is also the commercial center of Chiba. As of April 2012, the ward had an estimated population of 200,157 and a population density of 4,470 persons per km². The total area was 44.81 km², making it the most populous of the six wards of Chiba city.
Chūō Ward is located in southwestern Chiba city, facing Tokyo Bay. Much of the coastal area of the ward is built on reclaimed land.
The fortified residence (Inohana Castle) of the Chiba clan was located in the area of present-day Chūō Ward during the Kamakura period. The area was controlled by the Satomi clan during the Sengoku period, and was mostly tenryo territory ruled directly by the Tokugawa shogunate during the Edo period.
After the Meiji Restoration, the area of present-day Chūō Ward was divided on April 1, 1889 into the town of Chiba and villages of Soga, Miyako, Chishiro, and Oihama within Chiba District. Soga was raised to town status on May 23, 1890, and Chiba Town became Chiba City on January 1, 1921. On November 10, 1928, Oihama was raised to town status. The city of Chiba annexed Soga and Miyako on February 11, 1937, followed by Chishiro on February 11, 1944 and Oihama on February 11, 1955.
With the promotion of Chiba to a designated city with additional autonomy from Chiba prefecture and the central government on April 1, 1992, the city was divided into six wards, with the central ward designed Chūō Ward.
Chūō Ward is the center for industry and commerce for Chiba City. During the post-war era, the area developed largely as a company town to the neighboring steel works of Kawasaki Steel (JFE Steel Corporation).
Municipal elementary and junior high schools are operated by the Chiba City Board of Education (千葉市教育委員会).
