"Piggies" is a song by the English rock band the Beatles from their 1968 album The Beatles (also known as "the White Album"). Written by George Harrison as a social commentary, the song serves as an Orwellian satire on greed and consumerism. Among several elements it incorporates from classical music, the track features harpsichord and orchestral strings in the baroque pop style, which are contrasted by Harrison's acerbic lyrics and the sound of grunting pigs. Although credited to George Martin, the recording was largely produced by Chris Thomas, who also contributed the harpsichord part.

In the context of the turbulent political climate of 1968, "Piggies" was adopted by the counterculture as an anti-establishment theme song. It was also among the tracks on The Beatles that cult leader Charles Manson used as the foundation for his Helter Skelter theory of an American race-related countercultural revolution. Inspired especially by the line "What they need's a damn good whacking", Manson's followers left clues relating to the lyrics at the scenes of the Tate–LaBianca murders in August 1969.

"Piggies" has received widely varying responses from music critics, and its reputation suffered due to the association with Manson following the latter's trial in 1971. While some reviewers admire its musical qualities and recognise sardonic humour in the lyrics, others consider the song to be mean-spirited and lacking in subtlety. Harrison's demo of the song, recorded at his home in Surrey, was included on the Beatles' 1996 compilation Anthology 3. A live version by Harrison, reinstating a verse that was omitted from the studio recording, appears on his 1992 album Live in Japan. Folk singer and activist Theo Bikel and anarcho-punk musician Danbert Nobacon are among the artists who have covered "Piggies".
