The Spice Girls are an English girl group formed in 1994, consisting of Mel B ; Melanie C ; Emma Bunton ; Geri Halliwell ; and Victoria Beckham. With their "girl power" mantra, they redefined the girl-group concept by targeting a young female fanbase. They led the teen pop resurgence of the 1990s, were a major part of the Cool Britannia era, and became pop culture icons of the decade.

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.
