Tonari no 801-chan (となりの801ちゃん, Tonari no Yaoi-chan), literally translated as My Neighbor Yaoi-chan, is a Japanese four-panel Internet manga written and illustrated by Ajiko Kojima. The story centers on the relationship between a male otaku named Tibet and his yaoi-obsessed fujoshi girlfriend Yaoi whose obsession manifests itself as a small, green furry monster. Kojima originally started the manga on April 18, 2006 on his blog, and Ohzora Publishing released the first bound volume in December 2006; as of July 2016, ten volumes have been published. By June 2007, the first volume had sold 150,000 copies. The manga began serialization from the first chapter in Ohzora's Romance Tiara magazine in April 2009.

A shōjo manga re-imagining of the series entitled Tonari no 801-chan: Fujoshiteki Kōkō Seikatsu written and illustrated by Jin was serialized in Kodansha's Bessatsu Friend from November 28, 2007 to April 13, 2009. A spin-off manga series written and illustrated by Jun Minamikata called 801-shiki Chūgakusei Nikki: Tonari no Hina-chan started serialization in Romance Tiara in April 2009. A live action DVD-only film was produced in September 2007, and a drama CD was released in April 2008, and another followed in October 2008. An anime adaptation by Kyoto Animation was announced to air in Japan in 2009, but was unexpectedly canceled.

The green monster featured in Tonari no 801-chan has its origins in 801-chan (やおいちゃん, Yaoi-chan), the real-life mascot of the Misono Bridge 801 shopping center in northern Kyoto, Japan. The mascot, resembling Kyoto's well-known Kamo eggplant, was designed in late 2005 by a student at Kyoto Seika University. The shopping center itself was named for its 800-meter length, adding one to represent future expansion. Since the numbers 8-0-1 can be read in Japanese as ya-o-i (yaoi), the mascot soon became an Internet phenomenon. This brought the mascot to the attention of Ajiko Kojima, a Japanese blogger who took the mascot and slightly altered its appearance, using it as a basis for use his new webcomic Tonari no 801-chan in April 2006.
