Tenjho Tenge (天上天下, Tenjō Tenge?, lit. "Heaven and Earth") is an ongoing Japanese manga authored by Oh! great. The story primarily focuses on the members of the Juken Club and their opposition, the Executive Council, which is the ruling student body of a high school that educates its students in the art of combat. As the story unfolds, both groups become increasingly involved with an ongoing battle that has been left unresolved for four hundred years.

Tenjho Tenge was serialized in the Japanese magazine Ultra Jump published by Shueisha. It was adapted into a twenty-four episode anime series and aired on TV Asahi in Japan between April 1, 2004 to September 16, 2004. A two-episode original video animation was also made and aired on March 16, 2005. Both versions of the series have been licensed for release in the English language by two different companies. The manga has been licensed for publication by CMX, which came under criticism by fans for editing its sexual content. The anime series has been licensed and is being released by Geneon Entertainment.
