Morbid Visions is the debut studio album by Brazilian heavy metal band Sepultura, released on November 10, 1986, by Cogumelo Records. While later albums have a more political edge, Morbid Visions (along with the 1985 EP Bestial Devastation) is notable for Satanic themes and imagery. The band said many lyrics were fashioned after those of early extreme metal bands such as Venom and Celtic Frost (note the similarity of the album title to Morbid Tales).

The production quality of the album is rather poor. In the liner notes of Roadrunner's reissue of the album (which includes the tracks from Bestial Devastation), Cavalera admits that the band neglected to tune their guitars during the recording. They were only starting to learn English at this point, so they had to translate the lyrics word-for-word using a dictionary. All pre-1992 releases of Morbid Visions featured the first movement of Carl Orff's Carmina Burana ("O Fortuna") as an unnamed introduction. This composition was left off the CD re-release, probably due to copyright issues. This would mark the last appearance of the group's original lead guitarist Jairo Guedz.

The album, alongside Bestial Devastation, was re-recorded by Max and Igor Cavalera under the Cavalera Conspiracy name in 2023.
