The Number of the Beast is the third studio album by British heavy metal band Iron Maiden, released in March 1982. It saw the debut of vocalist Bruce Dickinson, and the final appearance of drummer Clive Burr. Since the release of The Number of the Beast and its subsequent tour, The Beast on the Road, "The Beast" has become an alternate name for Iron Maiden, and was later used in the titles of some of their compilations and live releases, including Best of the Beast and Visions of the Beast.
