Bōken Ō (冒険王, "Adventure King") was a monthly magazine for youth published by Akita Shoten between 1949 and 1983. It was among the first generation of children's comic magazines after World War II and was initially focused on publishing illustrated prose and emonogatari and then shifted to manga.
The magazine was initially founded under the title Shōnen Shōjo Bōkenō (少年少女冒険王) and was eventually renamed Bōken Ō. Nobumichi Akutsu acted as chief editor of the magazine for decades and worked extensively with Osamu Tezuka.
The magazine initially published some of the biggest hits of emonogatari during its peak, among them the science fiction series Sabaku no Maō by Tetsuji Fukushima. The magazine's editor gave Fukushima American comics as a reference for the series. In the early 1950s, it shifted more and more towards manga. The judo manga Igaguri-kun by Eiichi Fukui, serialized between 1952 and 1954, became the top selling manga series at the time, brought Bōken Ō to a circulation of 300.000 per month and fueled a surge in judo manga. In 1952, in response to the magazine's success, Manga Ō (漫画王, "Manga King") was established as a sister magazine to Bōken Ō.
