"Buttons" is a song by American girl group The Pussycat Dolls from their debut studio album PCD (2005). The song features Snoop Dogg and was written by Sean Garrett, Jamal "Polow da Don" Jones, Jason Perry, Nicole Scherzinger and produced by the former two alongside Ron Fair, Tal Herzberg and Young Smoke. The song was released as a digital download on April 11, 2006, as the album's fourth single and was serviced to contemporary hit radio in the United States on May 8, 2006. "Buttons" uses strong elements of Middle Eastern music in its production. Lyrically, the song involves Scherzinger speaking of a woman's desire to be undressed.

Critics were divided on "Buttons" with some complimenting the song's production, however, others criticized it followed the same formula of their previous singles. The song reached the top-five in countries such as Australia, Germany, and the United Kingdom. The song reached number one in Austria and in New Zealand, where it became their fourth consecutive number one single on the chart. It peaked at number three on the US Billboard Hot 100 and sold over two million copies in the United States, making The Pussycat Dolls the first female group in digital history to have three singles pass the two million mark in digital sales.

The sepia-toned music video directed by Francis Lawrence features The Pussycat Dolls in various dance sequences. Other scenes include Scherzinger by herself singing the verses. Since its release, "Buttons" has become a staple in Scherzinger's live performances. It was part of the set lists of the group's two major tours, PCD World Tour (2006–07), Doll Domination Tour (2009) and Scherzinger's own Killer Love Tour (2012). It was nominated for two awards at the 2006 MTV Video Music Awards for Best Dance Video and Best Choreography; it won the former award.
