Katsushika (葛飾区, Katsushika-ku^?) is a special ward located in Tokyo, Japan. It lies in the northeast of the ward area. The ward calls itself Katsushika City in English.

As of May 1, 2015, the ward has an estimated population of 444,356, and a population density of 12,770 people per km². The total area is 34.80 km².

Katsushika Ward is at the east end of Tokyo Metropolis. It is on an alluvial plain and it is low above sea level.

The ward office (Katsushika city hall) is located at Tateishi.

Katsushika has boundaries with three wards of Tokyo: Adachi, Edogawa and Sumida. The cities of Matsudo in Chiba Prefecture, and Misato and Yashio in Saitama Prefecture form the northeast border of the ward.

Major rivers in Katsushika include the Edogawa, Arakawa and Ayasegawa. Nakagawa and Shin-nakagawa flows through the ward.

Katsushika District was originally a division of Musashi Province. When the province was divided and reconfigured, the district was partitioned between Kita-Katsushika District (within Saitama Prefecture), Higashi-Katsushika District (within Chiba Prefecture) and the remainder was based in Tokyo Prefecture. Minami-Katsushika District conformed today's Katsushika Ward proper, plus Edogawa, Koto and Sumida wards.
