Labelle was an American girl band who were a popular vocal group of the 1960s and 1970s. The group was formed after the disbanding of two rival girl groups in the area around Philadelphia, in Pennsylvania, and Trenton, in New Jersey: the Ordettes and the Del-Capris, forming as a new version of the former group, then later changing their name to the Blue Belles (and further Bluebelles). The founding members were Patti LaBelle (formerly Patricia Holte), Cindy Birdsong, Nona Hendryx, and Sarah Dash.

As the Bluebelles, and later Patti LaBelle and the Bluebelles, the group found success with ballads in the doo-wop genre: "Down the Aisle (The Wedding Song)", "You'll Never Walk Alone", and "Over the Rainbow". After Birdsong departed to join The Supremes in 1967, the band, following the advice of Vicki Wickham, changed its look, musical direction, and style to re-form as Labelle in 1971. Their funk rock recordings of that period became cult favorites for their brash interpretation of rock and roll and for dealing with subjects not typically addressed by female black groups. Finally, after adapting glam rock and wearing outlandish space-age and glam costumes, the band found success with the proto-disco smash hit "Lady Marmalade" in 1974, leading to the album Nightbirds achieving gold success. They were the first contemporary pop group and first black pop band to perform at the Metropolitan Opera House. They were also the first black vocal group to appear on the cover of Rolling Stone.

Each of the band members later went on their own after the end of a tour in 1976, going on to have significant solo success. Nona Hendryx followed an idiosyncratic muse into a solo career that often bordered on the avant-garde; Sarah Dash became a celebrated session singer; and Patti LaBelle enjoyed a very successful Grammy-winning career, with several top-20 R&B hits between 1982 and 1997, a number-one pop hit with "On My Own", and lifetime-achievement awards from the Apollo Theatre, World Music Awards, and BET Awards.

The group reunited for their first new album in 32 years, Back to Now in 2008. They performed together regularly until the death of Dash on September 20, 2021, at the age of 76.
