"Do Somethin'" is a song recorded by American singer Britney Spears for her first greatest hits album, Greatest Hits: My Prerogative (2004). It was written and produced by Christian Karlsson and Pontus Winnberg (known collectively as Bloodshy & Avant), with additional writing by Henrik Jonback and Angela Hunte. Originally, the song was never intended to be released as a single. Spears, however, wanted to shoot a music video for it, and had to convince her record company. It was then released on February 14, 2005 by Jive Records as the second single from the album worldwide except North America. The dance-pop song features usage of electric guitars, and its lyrics allude to having a good time and not caring about other people's judgement.

"Do Somethin'" received generally favorable reviews from critics, and received comparisons to Gwen Stefani's 2004 single "What You Waiting For?". Although the single was not released in the United States, it charted on many of Billboard's component charts due to digital downloads, managing to reach number 100 on the Billboard Hot 100. It was also successful worldwide, reaching top ten positions in countries such as Australia, Denmark, Sweden and the United Kingdom. By the end of 2005, "Do Somethin'" was one of the best-selling singles in Australia and Belgium that year.

An accompanying music video, co-directed by Billie Woodruff and Spears, who is credited as her alter ego "Mona Lisa", portrays the singer and four female friends dancing and performing in a nightclub. The usage of a Louis Vuitton dashboard in the video resulted in a lawsuit against Jive Records, which ended with Louis Vuitton winning €80,000 in damages. The video was also banned in all European TV channels. Spears performed "Do Somethin'" during the The M+M's Tour in 2007, The Circus Starring Britney Spears in 2009 and Britney: Piece of Me in 2013–15.
