Body Language is the ninth studio album by Australian singer Kylie Minogue. It was released on 10 November 2003 by Parlophone. Following the commercial success of her eighth studio album Fever (2001), Minogue enlisted a diverse group of writers and producers to aid in creating a new album, including Cathy Dennis, Dan Carey, Emiliana Torrini, Johnny Douglas, and Kurtis Mantronik among others. Influenced by the musical works of the 1980s and artists like Prince and Scritti Politti, Body Language musically differs from Minogue's previous albums, which mainly featured disco-oriented dance-pop tracks, and instead explores genres like synth-pop, electroclash, R&B, and hip hop. Lyrically, the album touches upon themes of enjoyment, flirting, and sex.
 
Following its release, Body Language received generally favourable reviews from music critics, many of whom complimented Minogue for experimenting with new genres and the overall production of the album. Some critics, however, opined that many songs lacked catchy material and were not suitable for dancing. Commercially, Body Language peaked at number two on the albums chart of Australia and was certified double-platinum by the Australian Recording Industry Association (ARIA). In the United Kingdom, the album peaked at number six and was certified platinum by the British Phonographic Industry (BPI).
 
Although Body Language was not as much of a commercial success as Fever, it performed well nonetheless. In Minogue's native Australia, Body Language entered and peaked at number two on the albums chart and spent a total of 18 weeks on the chart. The Australian Recording Industry Association (ARIA) certified the album double-platinum for shipping 140,000 units in the country. In the United Kingdom, the album entered and peaked at number six on the UK Albums Chart with first week sales of 68,866 units. It remained inside the top 10 for one week, and for two weeks in the top 20. In total, it stayed on the chart for 30 weeks. Body Language was certified platinum by the British Phonographic Industry (BPI) on 28 November 2003, and had sold 398,035 copies by December 2007.
