Which Beyoncé song features the lyric-driven phrase “Who run the world”?

The Beyoncé song associated with the phrase “Who run the world” is “Run the World (Girls).”

The song was released as the lead single from Beyoncé's fourth studio album, 4, in April 2011. Its chorus repeats the rallying response “Girls,” giving the track its most recognizable hook.

The production draws on dancehall and electronic influences and prominently incorporates elements from Major Lazer's “Pon de Floor.” Beyoncé recorded the song with contributions from several writers and producers, including The-Dream, Switch, and Knowles.

The accompanying music video was directed by Francis Lawrence and used an elaborate post-apocalyptic visual style. The song is sometimes confused with “Independent Women Part I,” Destiny's Child's earlier empowerment anthem, but “Run the World (Girls)” is a Beyoncé solo release.
