Shueisha Inc. (株式会社集英社, Kabushiki Gaisha Shūeisha, "Shueisha Publishing Co., Ltd.") is a Japanese book and video game publisher headquartered in Chiyoda, Tokyo, Japan. The company was founded in 1925 as the entertainment-related publishing division of Japanese publisher Shogakukan. The following year, Shueisha became a separate, independent company.

Magazines published by Shueisha include Weekly Shōnen Jump, Weekly Young Jump, Non-no and Ultra Jump. Shueisha, along with Shogakukan, owns VIZ Media, which publishes manga from all three companies in North America.

In 1925, Shueisha was created by major publishing company Shogakukan (founded in 1922). Jinjō Shōgaku Ichinen Josei (尋常小學一年女生) became the first novel published by Shueisha in collaboration with Shogakukan—the temporary home of Shueisha. In 1927, two novels titled Danshi Ehon, and Joshi Ehon were created. In 1928, Shueisha was hired to edit Gendai Humor Zenshū (現代ユーモア全集, Gendai Yūmoa Zenshū), a compilation. Gendai Humor Zenshū continued 12 volumes, some issues being Joshi Shinjidai Eishūji-chō and Shinjidai Eishūji-chō (新時代英習字帳). In the 1930s another novel called Tantei-ki Dan was launched and Gendai Humor Zenshū was completed in 24 volumes. In 1931 two more novels were launched, Danshi Yōchien and Joshi Yōchien.

After World War II, Shueisha started publishing a manga line called Omoshiro Book. Omoshiro Book published a picture book called Shōnen Ōja, which became a huge hit among boys and girls. The first full volume of Shōnen Ōja was released as Shōnen Ōja Oitachi Hen, which became an instant best-seller.
