Full Moon o Sagashite (満月(フルムーン)をさがして, Furu Mūn o Sagashite, also titled Full Moon and Looking for the Full Moon in English) is a Japanese manga series written and illustrated by Arina Tanemura. It was serialized in the shōjo manga magazine Ribon from January 2002 to June 2004 and collected in seven tankōbon volumes.

The series was adapted into an anime television series produced by Nihon Ad Systems, which ended before the manga was completed, as well as an original video animation distributed through Ribon. The anime series was broadcast on TV Tokyo.

Viz Media acquired English distribution rights to both the manga and the anime, with the first 28 episodes of the anime released.

AnimEigo acquired the North American home video rights for the anime, and is releasing the complete series in two Blu-ray sets. The previously unreleased English dubbed episodes will also be included.
