"Children of the Grave" is a song by English heavy metal band Black Sabbath, from their 1971 album Master of Reality. The song lyrically continues with the same anti-war themes brought on by "War Pigs" and "Electric Funeral" from Paranoid.

Black Sabbath were an English rock band formed in Birmingham in 1968 by guitarist Tony Iommi, drummer Bill Ward, bassist Geezer Butler and vocalist Ozzy Osbourne. They are often cited as pioneers of heavy metal music. The band helped define the genre with their first three albums Black Sabbath, Paranoid and Master of Reality (1971). Following Osbourne's departure in 1979, the band underwent multiple line-up changes, with Iommi being the only constant member throughout their history.
