The Best of Black Sabbath is a compilation album by the English heavy metal band Black Sabbath, released in 2000 on the Sanctuary Records label. Its 32 songs are presented chronologically from the band's first 11 studio albums, spanning the years 1970 to 1983. Black Sabbath's classic six-album run, from their debut Black Sabbath (1970) to Sabotage (1975), is represented by three to six songs from each album. Original vocalist Ozzy Osbourne's subsequent final two albums with the band, Technical Ecstasy (1976) and Never Say Die! (1978), are represented by one and two songs, respectively. Replacement Ronnie James Dio's early 1980s stint fronting the band on two albums is acknowledged with the title track of Heaven and Hell (1980) and a track from The Mob Rules (1981). The compilation closes with a song from the band's attempted rebirth, Born Again (1983), former Deep Purple vocalist Ian Gillan's sole album with the band. The Best of Black Sabbath does not include any later material with vocalists Glenn Hughes, Tony Martin (1986–96) or the returning Dio.
