Shōnen manga is an editorial category of Japanese comics targeting an audience of adolescent boys. It is, along with shōjo manga, seinen manga, and josei manga, one of the primary editorial categories of manga. Shōnen manga is traditionally published in dedicated manga magazines that exclusively target the shōnen demographic group.

Manga are comics or graphic novels originating from Japan. Most manga conform to a style developed in Japan in the late 19th century, and the form has a long history in earlier Japanese art. The term manga is used in Japan to refer to both comics and cartooning. Outside of Japan, the word is typically used to refer to comics originally published in Japan.
