"Do It" is a song by Canadian recording artist Nelly Furtado for her third album, Loose (2006). It was produced by Timbaland and Nate "Danja" Hills. It features a prominent influence of 1980s dance-pop music and sexually suggestive lyrics, in which the song's protagonist asks a lover to satisfy her physically.
Alongside a remix featuring rapper Missy Elliott, the song was released as the fifth single from Loose in North America in mid-2007, and Furtado co-directed the accompanying music video. "Do It" reached the top twenty in Canada and was a number-one club hit in the United States, where it became Furtado's lowest peaking single on the Billboard Hot 100; it reached higher positions on charts on mainland Europe.
In January 2007, it was revealed that Timbaland plagiarized the synth line in "Do It" from an earlier track by Finnish demoscener Janne Suni—for more information, see 2007 Timbaland plagiarism controversy.
