Katsushi Katsukawa is a Japanese manga artist and original creator born in 1950 in Ena, Gifu Prefecture, Japan. He made his professional debut as a solo manga artist in 1976 with the work My Little Brother, which was published in Young Comic magazine. Much of his subsequent production has been with the publisher Shonengahosha.

Katsukawa is best known as the creator of the manga Mabo-chan Ryokōki, also known as Little Mabo's Travels. This manga served as the original work for the television anime series Maruboshi Mabo-chan, which was produced by Studio Comet and broadcast in 1992. The anime adaptation, however, was not a direct one-to-one translation of the manga. The original manga series consisted of only four episodes, so the anime production team created many new episodes that differed from the original source material. These new episodes were developed by using or reworking material from other works by Katsukawa and by introducing original characters that do not appear in his manga.

Beyond his work on Mabo-chan Ryokōki, Katsukawa has created other manga series. These include Ramune no Rapsody, which was serialized in Young King magazine, and Harukana Mori Monogatari: Raito-kun, serialized in Hero Magazine. He was also the manga artist for Manga Rakugo Mono Ga Tari Jiten, a book that adapts forty-one traditional Japanese rakugo stories into manga form.

Katsukawa is recognized for a distinctive and personal artistic style that draws influence from American children's comics of the 1930s. His artwork is characterized by a lack of straight lines in backgrounds, creating a distorted effect similar to a wide-angle or fish-eye lens. This visual approach extends to other elements of his manga, such as speech bubbles and credit designs, which are often shaped into figures. While his graphic style is frequently noted as being more remarkable than the narrative plots themselves, his work is generally situated within the comedy genre and appeals to a younger audience.
