Haruhi Suzumiya is a Japanese light novel series written by Nagaru Tanigawa and illustrated by Noizi Ito. It was first published in 2003 by Kadokawa Shoten in Japan with the novel The Melancholy of Haruhi Suzumiya, and has since been followed by 11 additional novel volumes, an anime television series adaptation produced by Kyoto Animation, four manga series, an animated film, two original net animation series and several video games.

Anime is hand-drawn and computer-generated animation originating from Japan. Outside Japan and in English, anime refers specifically to animation produced in Japan. However, in Japan and Japanese, anime describes all animated works, regardless of style or origin. Many works of animation with a similar style to Japanese animation are also produced outside Japan. Video games sometimes also feature themes and art styles that are sometimes labelled as anime.
