The official title of the album fans commonly call The Black Album is Metallica.
It is the band's fifth studio album and is formally self-titled, using the group name as the album title. The nickname The Black Album became widespread because of the stark black packaging, the dark design, and comparisons with other famous self-titled albums known by informal color-based names.
The album's cover features the band's logo and a subtle coiled snake, associated with the song “Don't Tread on Me.” The restrained artwork contrasted with the highly detailed covers of several earlier Metallica records.
People sometimes use The Black Album as though it were the official title, especially in conversation and retail listings. It is an accepted nickname, but the canonical album title remains Metallica. The distinction matters in discographies, citations, and anniversary references.
