Sepultura (Portuguese: [ˌsepuwˈtuɾɐ], "grave") is a Brazilian heavy metal band formed in Belo Horizonte in 1984 by brothers Max and Igor Cavalera. Initially a black metal band, they were a major force in the groove metal, thrash metal and death metal genres during the late 1980s and early 1990s, with their later experiments drawing influence from alternative metal, world music, nu metal, hardcore punk and industrial metal. Sepultura is also considered part of the second wave of thrash metal acts from the late 1980s to early-to-mid-1990s.

The band has gone through several membership changes throughout its 40-year existence, with Max and Igor Cavalera departing in 1996 and 2006, respectively. Sepultura's current lineup consists of singer Derrick Green, who replaced Max in 1997, guitarist Andreas Kisser, bassist Paulo Jr. and drummer Greyson Nekrutman, who replaced Eloy Casagrande in 2024. Since Igor Cavalera's departure in 2006, there have been no original members left in the band. Although Paulo Jr. joined Sepultura shortly after its formation in late 1984 and is the longest serving member, he did not perform on any of the band's studio albums until Chaos A.D. (1993). Kisser, who replaced onetime guitarist Jairo Guedz, has appeared on all of Sepultura's albums since their second full-length Schizophrenia (1987); he also recorded bass guitar until Chaos A.D.. In March 2024, after four decades together, the band began what has been announced as a year-and-a-half long farewell tour, after which they will disband.

Sepultura has released fifteen studio albums to date, the latest being Quadra (2020). The band has sold over three million units in the United States and almost 20 million worldwide, gaining multiple gold and platinum records around the globe, including in countries as diverse as France, Australia, Indonesia, the United States, Cyprus, and their native Brazil.
