Manga (in kanji 漫画; in hiragana まんが; in katakana マンガ, listen (help·info)) (English: /ˈmɑːŋɡə/) consist of comics and print cartoons (sometimes also called komikku コミック), in the Japanese language and conforming to the style developed in Japan in the late 20th century. In their modern form, manga date from shortly after World War II, but they have a long, complex pre-history in earlier Japanese art.

In Japan, people of all ages read manga. The genre includes a broad range of subjects: action-adventure, romance, sports and games, historical drama, comedy, science fiction and fantasy, mystery, horror, sexuality, and business and commerce, among others. Since the 1950s, manga have steadily become a major part of the Japanese publishing industry, representing a 481 billion yen market in Japan in 2006 (approximately $4.4 billion dollars). Manga have also become increasingly popular worldwide. In 2006, the United States manga market was $175–200 million. Manga are typically printed in black-and-white, although some full-color manga exist (e.g. Colorful). In Japan, manga are usually serialized in telephone book-size manga magazines, often containing many stories, each presented in a single episode to be continued in the next issue. If the series is successful, collected chapters may be republished in paperback books called tankōbon. A manga artist (mangaka in Japanese) typically works with a few assistants in a small studio and is associated with a creative editor from a commercial publishing company. If a manga series is popular enough, it may be animated after or even during its run, although sometimes manga are drawn centering on previously existing live-action or animated films (e.g. Star Wars).

"Manga" as a term used outside Japan refers specifically to comics originally published in Japan. However, manga and manga-influenced comics, among original works, exist in other parts of the world, particularly in Taiwan ("manhua"), South Korea ("manhwa"), and the People's Republic of China, notably Hong Kong ("manhua"). In France, "la nouvelle manga" has developed as a form of bande dessinée drawn in styles influenced by Japanese manga. In the U.S., people refer to manga-like comics as Amerimanga, world manga, or original English-language manga (OEL manga).
