Bunkyō is a special ward in the Tokyo Metropolis in Japan. Situated in the middle of the ward area, Bunkyō is a residential and educational center. Beginning in the Meiji period, literati like Natsume Sōseki, as well as scholars and politicians have lived there. Bunkyō is home to the Tokyo Dome, Judo's Kōdōkan, and the University of Tokyo's Hongo Campus. Bunkyō has a sister-city relationship with Kaiserslautern in the Rhineland-Palatinate of Germany.

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.
