"Only Girl (in the World)" is a song by recording artist Rihanna, from her fifth studio album Loud (2010). The song was released as the album's lead single on September 10, 2010 through Def Jam. It was written by Crystal Johnson, Norwegian production duo Stargate and Sandy Vee, and produced by StarGate and Vee. Musically, "Only Girl" is an up-tempo dance-pop song which incorporates elements of Europop. The song became the first to be completed for the album, and Rihanna chose it for inclusion before recording it.
"Only Girl" was well received by music critics, many of whom complimented its beat, as well as the direction of moving away from the darker themes which were present on Rihanna's previous album Rated R (2009). "Only Girl" was a commercial success. In the United States, the song debuted at number seventy-five on the US Billboard Hot 100 and peaked at number one in its eleventh week, giving Rihanna her ninth number one single on the chart. "Only Girl" topped the charts in fifteen countries, including Australia, Austria, Canada, Hungary, Ireland, Italy, New Zealand, Norway, Poland and the United Kingdom. It also attained top five positions in Belgium, France, Germany, the Netherlands and Switzerland and peaked in the top ten of charts in twenty-seven countries worldwide. The song won the award for Best Dance Recording at the 53rd Grammy Awards.
The song's accompanying music video, directed by Anthony Mandler, uses the simplistic theme of predominantly focusing on Rihanna frolicking on a hillside with life size flowers placed near her with an array of artistic sceneries and props. The song was performed on Saturday Night Live and at the 2010 American Music Awards as part of a medley with "Love the Way You Lie (Part II)" and "What's My Name?" in the United States. Rihanna also performed the song on The X Factor and 2011 Brit Awards in the United Kingdom. American singer Katy Perry covered the song during her California Dreams Tour (2011/2012) and British boy band One Direction performed the track on The X Factor.
