“Right Round” is a song performed by American rapper Flo Rida featuring pop singer Kesha from R.O.O.T.S., his second studio album. It was released to radio as the album's lead single on January 27, 2009 and was digitally released on February 10 by Poe Boy Entertainment and Atlantic Records. The song lyrically speaks of developing a crush on a woman at a strip club, while sampling the 1984 Dead or Alive song “You Spin Me Round (Like a Record)” in its hook. According to one of the song's writers, the chorus refers to oral sex. Electropop singer Kesha contributed guest vocals to the song, but was only credited internationally. In one of the verses Flo Rida says "She's Taking My Bank, Fool" which is a reference to Coolio's "Gangsta's Paradise".

The song received mostly negative reviews from critics, who claimed it was kitsch and misogynistic. However, it was a commercial success, reaching the top ten of the charts in nineteen countries worldwide. In the United States, it became Flo Rida's second number-one single and broke the record for first-week sales when it was released to digital retailers. The single's accompanying music video was directed by Malcolm Jones and nominated for an MTV Video Music Award. It was also used in the end credits of the movie The Hangover.
