Tenjho Tenge (Japanese: 天上天下, Hepburn: Tenjō Tenge; lit. 'Heaven and Earth'),[a] also written as Tenjo Tenge, is a Japanese manga series written and illustrated by Oh! great. It was serialized in Shueisha's seinen manga magazine Ultra Jump from July 1997 to August 2010, with its chapters collected in 22 tankōbon volumes. 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.

It was adapted into a 24-episode anime television series broadcast on TV Asahi from April to September 2004. A two-episode original video animation (OVA) was released in March 2005.

Both versions of the series have been licensed for release in English language by two different companies. The manga was licensed and released by CMX beginning in 2005, which came under criticism by fans for editing its sexual content. When CMX closed down in 2010, after releasing 18 volumes, Viz Media picked up the rights and completed their own uncut release of the series in 2013. The anime was licensed and released by Geneon Entertainment, also beginning in 2005, however, it is now licensed by Discotek Media.

The plot begins with Souichiro Nagi and his childhood best friend Bob Makihara going to their first day of high school at Toudou Academy. They had intended to rule the school by beating up anybody that got in their way, as they had done at their previous schools. They soon learn that Toudou is no ordinary high school, but rather a school that was founded to teach and integrate different fighting styles. Its students are skilled in the various arts of combat with some students possessing supernatural abilities, such as pyrokinesis, precognition, and superhuman strength based on the abilities to use their "spirit" or "ki" in Japanese. After an altercation with the Executive Council, Souichiro and Bob join the only surviving club that opposes them, the Juken club. As the storyline develops, both groups find they are becoming increasingly involved in a long enduring conflict that was left unresolved from the Japanese feudal era by some of the characters' ancestors.
