"Sabbath Bloody Sabbath" is a heavy metal song by British group, Black Sabbath. It is the title track of the band's fifth album Sabbath Bloody Sabbath. It was released on the album in 1973. The song is the opening track on the album. It appears as the 12th track in the 2006 Black Sabbath Greatest Hits 1970-1978 album. The main riff in the song has been recognized as "the riff that saved Black Sabbath" due to the fact that Tony Iommi was suffering from writer's block at the time. The band's music was based around his writing, and they resorted to drastic measures (including renting out a supposedly haunted castle to live in) to inspire him. When he wrote the riff to Sabbath Bloody Sabbath, the rest came freely and Sabbath was saved.

Sabbath Bloody Sabbath starts out with a more progressive sound and riff. The lyrics and sound to the song appears to be inspired by the band's frustration with their former manager and the sense of betrayal they had felt at times. The song deals with a person who is betrayed and lied to, and disenfranchised from what seems to be his native society(1st 2 lines, last stanza "Everything around you, what's it coming to")

Velvet Revolver and former Guns 'N' Roses guitarist Slash has stated that "Sabbath Bloody Sabbath" is his favorite Black Sabbath riff and song. When at The Download Festival in 2005 where both Velvet Revolver and Black Sabbath were playing, Slash stated that he would be "Putting in a request with the band for Sabbath Bloody Sabbath"

The song has been dropped from the band's sets. It was rarely played live in the 70s, and when the band reunited they only performed the first half in completion, with Ozzy dropping out of the song and not singing the final two verses. By the year 2000 it was dropped from their set entirely, until it emerged a few years later when the band played the riff a few times as an introduction to "Paranoid".
