Blackpink is a South Korean girl group formed by YG Entertainment and consisting of members Jisoo, Jennie, Rosé, and Lisa. Cited as the "biggest girl group in the world", they are considered the most successful Korean girl group internationally and a leading force in the Korean Wave. They are stylistically associated with the "girl crush" concept in K-pop—exploring themes of self-confidence and female empowerment.

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.
