Music journalist
Martin Popoff has called the song an "ugly, antiwar classic now considered one of Sabbath's top two or three most enduring compositions". Steve Huey of
AllMusic called the song a "
standard".
Kelefa Sanneh wrote, "What is memorable is the way Osbourne evokes not merely war's cost but its seductive appeal. Part of what made Black Sabbath seem new was a disinclination to uplifting, or hopeful, or self-righteous." "War Pigs" is widely considered one of Black Sabbath's greatest songs. In 2020,
Kerrang! ranked the song number four on their list of the 20 greatest Black Sabbath songs, and in 2021,
Louder Sound ranked the song number one on their list of the 40 greatest Black Sabbath songs. "War Pigs" was ranked the best Black Sabbath song by . The song is notable for its publication in the American folk music magazine
Broadside, which normally did not feature rock songs. The song's guitar riff largely inspired that of
Arctic Monkeys' 2014 single
"Arabella", to the extent that the band often perform an interlude of the song, to enable front man
Alex Turner to pick up his guitar in time for his solo. In more recent times, when performing a live rendition of Arabella, the Arctic Monkeys often end the live performance of the song with a tease of the songs riff.
War Pigs was featured in the credits of the 2014 film
300: Rise of an Empire, a sequel to the 2007 film
300.
War Pigs was one of the 40 songs featured in the Music Monday series of the
Newseum, and thus part of the
Reporting Vietnam exhibit as a major musical reflection of the time.
WWE has used the song for their
NXT TakeOver: WarGames events, as well as their
Survivor Series WarGames event since the 2022 edition. Several of the
University of Arkansas' sports teams, known as the
Razorbacks (a term for
feral pigs, which are known for their ferocity), use
War Pigs as their run-out/tunnel walk music. The song is also part of the regular repertoire of the
Razorback Marching Band. In 2023,
Rolling Stone ranked the song number five on their list of the 100 greatest heavy metal songs.
Judas Priest has used
War Pigs as their walk on music since late 2011. On July 2nd, 2025, Judas Priest released a cover of
War Pigs on their official YouTube channel. Black Sabbath also posted the video to their official YouTube channel. During the
2026 Grammy Awards ceremony, the song was played live during the "in memoriam" portion of the show with a band consisting of musicians from other famous bands, including
Guns n Roses guitarist
Slash, vocalist
Post Malone, and
Red Hot Chili Peppers drummer
Chad Smith, in order to commemorate the death of Ozzy Osbourne. ==Personnel==
