"Feedback" is a song by American recording artist Janet Jackson, released as the lead single from her tenth studio album, Discipline. It was written and produced by Rodney "Darkchild" Jerkins and D'Mile, with additional writing from Tasleema Yasin and LaShawn Daniels. "Feedback" fuses electropop and dance, while also incorporating elements of Eurodance and hip hop. Its lyrical composition is based on Jackson's sexual bravado; questioning the listener while responding with a chant of "sexy, sexy." Its chorus compares her body to instruments such as a guitar and amplifier, using metaphors to demonstrate sexual climax.

"Feedback" received acclaim from critics, who praised its sonic innovation and contrast from her prior release, commending Jackson as "back in the form that made her a pop superstar." It reached number nineteen on the Billboard Hot 100 and peaked atop the Hot Dance Club Play chart, becoming her biggest hit since "Someone to Call My Lover." Internationally, it topped the charts in South Korea and reached the top ten in Canada, Greece, Slovakia and South Africa.

Its music video, directed by Saam Farahmand, portrays Jackson jumping from various planets before dancing among an unidentified white liquid. The video received positive reception from critics, who praised its galactic visuals and choreography. Jackson performed "Feedback" on Good Morning America, The Ellen DeGeneres Show, and TRL, the latter being Jackson's first admittance to MTV since her Super Bowl performance incident. "Feedback" received three nominations at the International Dance Music Awards.
