Animetal Marathon IV is the fourth full album by Japanese novelty heavy metal band Animetal, released through Cutting Edge Records on September 12, 2001. The album consists of a non-stop marathon of metal covers of anime themes from the 1970s, 1980s, and 1990s. It also marked the return of Animetal after a two-year hiatus. However, it was also the last to feature lead guitarist She-Ja, who was then replaced by Syu on the band's subsequent releases.
