Rozen Maiden (Japanese: ローゼンメイデン, Hepburn: Rōzen Meiden) is a Japanese manga series written and illustrated by Peach-Pit. It was serialized in Monthly Comic Birz between the September 2002 and July 2007 issues. The individual chapters were collected and released into eight tankōbon volumes by Gentosha. The eight volumes were localized to North America by Tokyopop between March 2003 and June 2007. The story follows Jun Sakurada, a middle school student who withdrew from society after suffering persecutions from his classmates. Following his withdrawal, he is chosen to become the master to a Rozen Maiden named Shinku. Rozen Maidens are seven sentient porcelain dolls who compete against each other to become a perfect doll dubbed as Alice.

Rozen Maiden received a sequel under the series' katakana title. It was serialized in Shueisha's Weekly Young Jump between April 2008 and January 2014. Rozen Maiden has spun off anthology manga and novel stories, art books, and four anime series; the four anime series are titled Rozen Maiden, Rozen Maiden: Träumend, Rozen Maiden: Ouvertüre, and Rozen Maiden: Zurückspulen. Tokyo Broadcasting System were the producers for the anime with Nomad as the animation studio for the first three series and Studio Deen for Zurückspulen. The anime adaptions resulted in several audio disc releases and three video games.

In 2007, Geneon Entertainment USA licensed the first two anime series for North American release and had later signed Funimation on as a distributor, after shutting down in September 2007. In 2011, Sentai Filmworks acquired both seasons as well as the third series; they made the three series available for streaming on Anime Network.
