"Right Round" is a dance-pop song performed by American rapper Flo Rida from R.O.O.T.S., his second studio album. It was released as the lead single from the album on February 10, 2009 by Poe Boy Entertainment and Atlantic Records. The song lyrically speaks of developing a crush on a woman at a strip club, while musically incorporating a sample of the 1984 Dead or Alive song "You Spin Me Round (Like a Record)" in its hook. Pop singer Kesha contributed uncredited guest vocals to the song.

The song received mostly negative reviews from critics, who claimed it was cheesy 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.

"Right Round" was written by Flo Rida, Dr. Luke, Allan Grigg, Justin Franks, Philip Lawrence, Bruno Mars, Aaron Bay-Schuck, Pete Burns, Steve Coy, Mike Percy and Tim Lever. It was produced by Luke and Koool Kojak and features uncredited guest vocals from American pop singer Kesha. According to Flo Rida, the song is about "a young lady, she might be in the strip club and she's got my head spinning round, [...] Or any young lady that I might see walking past me that's getting my attention. She got it going on! I'm going crazy over her."

The song contains a sample of Dead or Alive's 1984 single "You Spin Me Round (Like a Record)". Flo Rida explained that he listened to that and similar records growing up as a result of the varying music genres his seven sisters listened to. However, Mike Caren, his A&R, was the one who brought the sample to his attention. As R.O.O.T.S.was Flo Rida's second studio album, he wanted to show listeners musical growth by "broaden[ing] my horizons," which was why he decided to record the song. After Luke produced the sample, the song was recorded. It was recorded primarily at Conway Studios in Hollywood, California, with additional recording at Atlantic Studios, also located in Hollywood.

Musically, "Right Round" uses the recurring pop rap themes of Flo Rida's music; specifically, similarities were noted between the song and "Low" (2007), with Allmusic reviewer David Jeffries calling "Right Round" its "heir apparent". The song is "swaggering" and "bass-heavy", according to Leah Greenblatt of Entertainment Weekly. The lyrics discuss being in a strip club with friends and tossing money at a woman performing a striptease. Additionally, the chorus line "You spin my head right round, right round / When you go down, when you go down, down" can be interpreted as a reference to fellatio. The song's sexual themes have been compared to those of "If U Seek Amy" (2009) by Britney Spears.

Reviews for "Right Round" were mostly negative. A reviewer for The New York Timescalled the song "[b]ionic and empty". In a review of R.O.O.T.S., Ken Capobianco of The Boston Globestated, "His music is pure ear candy that must make Britney [Spears] envious, yet he wants to come off as a thug." He continued that it is unlikely that "Right Round" would be heard on Brooklyn's streets 15 years prior to its release, calling it "as hard as Jell-O." Alex Fletcher of Digital Spy stated in his review of the song, "It's pretty difficult to ruin a pop classic, but Flo Rida gives it a pretty good stab here." He added that "Right Round" is "[f]illed with more misogyny than a 1970s working mens' club", and called it "an unpleasant affair that's only saved from the trashcan by its sample." Fletcher concluded, "The fuzzy synths, electro beats and infectious chorus hook sung by Ke$ha are almost enough to fool the casual listener into enjoying themselves. But sadly it's never too long before Flo Rida turns up again to spoil things." Simon Vozick-Levinson of Entertainment Weeklycalled the song "a horrendous rap remake of Dead or Alive's 'You Spin Me Round (Like a Record).'" Noting that the song was, at the time, the number-one single on the Hot 100, he added, "What does all this say about us as a society? Mainly that we really, really enjoy cheesetastic '80s hair-pop hits in whatever form we can get 'em, I guess."

There were some positive reviews, however. One such review came from Fraser McAlpine of BBC, who opened, "It's one of the fundamental laws of pop, anything which tips a nod to 'You Spin Me Round (Like A Record)' by Dead Or Alive is going to be worth a listen." He continued, "Even though this is just a song written from the perspective of a randy man watching a pole-dancer and bragging about how much money he has [...] in a manner which would make Akon blush, there's just something kind of cute about the whole thing." McAlpine attributed this to the song's "Tigger-beat", explaining, "How can anything too sordid be going on when everyone is bouncing around like they're on spacehoppers?" Bill Lamb of About.com commented, "You will hear echoes of another pop classic, but the new song stands on its own feet." However, he noted that while pop music fans would appreciate it, hip hop listeners would likely dismiss it, and he added that "[i]t's not groundbreaking by any means".

In the United States, "Right Round" debuted at number seventy-four on the BillboardHot 100 based solely on airplay. The next week, it rose sixteen positions to chart at number fifty-eight.

The song's accompanying music video was shot in Miami, Florida and directed by Malcolm Jones. Kesha was asked to appear in the video, but declined; in an interview with Esquiremagazine, she said, "They [Flo Rida's team] wanted me in the video, and I said, 'Nah, I want to make my own name for myself.'" The video begins with Flo Rida standing on a revolving circular platform, while his name appears in gold on a screen behind him. A young woman then joins him on the platform, with shots alternating between the two together and each individually. During the first verse, the screen behind him alternates between images of a rotating globe and locations such as Tokyo, Paris and New York City. Shortly after, the silhouettes of three women appear behind Flo Rida while the clip is intercut with shots of a rotating disco ball and several women on a circular bed. Several women are then seen dancing on or around cars while Flo Rida stands in front of them. A waitress comes in to serve them an unidentified beverage. As the video ends, Flo Rida is seen once again on the circular platform while the screen behind him shows a red background with a gold Poe Boy Entertainment sticker. The video was nominated for Best Hip-Hop Video at the 2009 MTV Video Music Awards, but lost to Eminem's "We Made You" (2009).
