"War Pigs" is an anti-war song by British heavy metal band Black Sabbath from their 1970 album, Paranoid. The song talks about war and the absurdities of those who make war without regard to the powerless people who are sent to die. It's sometimes called a protest song.

As explained in the liner notes of the band's live album Reunion, the original title of the song was Walpurgis, and it dealt with the witches' sabbath. The title, lyrics, and theme were subsequently changed during the recording of Paranoid. An early version, with its original theme, can be found on Ozzy Osbourne's compilation The Ozzman Cometh.

It is the opening track on Paranoid, Black Sabbath's best selling album. It can also be found on every live and compilation album by the band (except Cross Purposes Live) along with "Paranoid" itself and "Iron Man". The outro to War Pigs has its own name: "Luke's Wall", and features a more melodic tone than the rest of the song, with heavy use of the Aeolian (natural minor) mode. It should also be noted although the guitar and bass are in E natural minor for most of the song, Ozzy's singing is actually in E Mixolydian mode.

Originally intended to be the title-track, the name of the album was changed to Paranoid, as Black Sabbath's record company feared a backlash by supporters of the Vietnam War. It is one of Black Sabbath's most popular songs, and is still played on Classic Rock stations regularly. The riff, as with most Sabbath songs, is powerful and memorable, as are the eerie verses, which feature Osbourne singing alone (using a melody cribbed from their earlier "Behind The Wall Of Sleep") and punctuated at every line by a guitar lick. At the end, there's a speeding-up effect.

Warpigs is a Hungarian rock band formed in 1993. After several member changes, the classic lineup from 1997 consisted of the two Eszenyi brothers, György Újhelyi and Bálint Gátos. Supported acts such as Bon Jovi, Biohazard, KISS. They split in 1999 with singer Péter Eszenyi leaving the band. Several singers were drafted to replace him, including Marci Lombos and Chris Alexander, but none of them stayed for long. In 2006 they started playing together again with Eszenyi as singer, having one or two gigs every year since.

Their first video, Szandál, was directed by Nimród Antal, who later used the same idea for his first major motion picture Kontroll (2003).

Their second video for the song Monte Carlo, directed by Márton Nyitrai, won MTV Europe's Best Hungarian Music Video award in 1999.

Gábor has since formed a new band called 17 Trees in late 2006.
