Crescent is the fourth full-length studio album released by Japanese solo artist Gackt on December 3, 2003. It is conceptually linked to its predecessor Moon and comes with booklets for both records (Moon did not originally contain one). Crescent also features a duet with L'Arc-en-Ciel vocalist Hyde for "Orenji no Taiyou" with whom Gackt co-starred in the 2003 movie Moon Child.
