Moon is the third full-length studio album released by Japanese solo artist Gackt on June 19, 2002. Instead of a booklet, the album comes with a printed note by the artist, asking readers to "sense" the record's story, rather than analyzing the lyrics. The booklet was eventually included in the packaging of Moon's 2003 follow-up Crescent. Both albums are conceptually linked, as well as his more recent albums Diabolos and Last Moon from the "Moon Saga".
