Labelle was an American funk rock band that originated out of the Blue Belles, a girl group who were a popular vocal group of the 1960s and 1970s. The original 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. The founding members were Patti LaBelle, Cindy Birdsong, Nona Hendryx, and Sarah Dash.

A girl group is a music act featuring several female singers who generally harmonize together. The term "girl group" is also used in a narrower sense in the United States to denote the wave of American female pop music singing groups, many of whom were influenced by doo-wop and which flourished in the late 1950s and early 1960s between the decline of early rock and roll and start of the British Invasion. All-female bands, in which members also play instruments, are usually considered a separate phenomenon. These groups are sometimes called "girl bands" to differentiate, although this terminology is not universally followed.
