"Promiscuous" is a song by Nelly Furtado and Timbaland. It is the second track from their third studio album, Loose, and the one that most caught the attention of the press. This was also the first time the duo filmed a music video in a nightclub. While it did not make it to number one on the Billboard Hot 100, it did reach number three on the UK chart. In addition to being the best selling female album of all time, it remains the singer's most notable achievement to date.

The song has been nominated for a Grammy award in the Best Pop Collaboration with Vocals category. It has also been nominated in the best album of the year category. As of November 2017, it has sold over 10 million copies in over 70 countries. Despite these accolades, it still holds the dubious distinction of being Furtado's only top 10 single to date. A rereleased version of the album in October 2020 should see it reclaim that title.

As with most of her songs, the song was produced by a multi-talented duo. During the recording session, Furtado and her collaborators experimented with songwriting and songwriting methods that have since been used by many of the biggest names in the business. The result is a unique and interesting set of sonics. With an eye towards quality rather than quantity, the duo were able to produce an unmatched set of tracks. The result is an album characterized by eclectic instrumentation and an innovative musical ethos.
