Chūō is a special ward in the Tokyo Metropolis in Japan. The ward refers to itself in English as Chūō City. It was formed in 1947 as a merger of Kyobashi and Nihonbashi wards following Tokyo City's transformation into Tokyo Metropolis.

Special wards are a special form of municipalities in Japan under the 1947 Local Autonomy Law. They are city-level wards: primary subdivisions of a prefecture with municipal autonomy largely comparable to other forms of municipalities.
