No Strings Attached is the second studio album by American boy band NSYNC, released on March 21, 2000 by Jive Records. Looking to distinguish their music from that of their labelmates, its music incorporates pop and R&B styles. Prior to the release of the album, NSYNC separated from their management Trans Continental and their label RCA Records; its title is a play on the idea of independence from corporate control. Contributions to the album's production came from a wide range of producers, including group members Justin Timberlake and JC Chasez and new collaborators Kristian Lundin, Jake Schulze, Rami Yacoub, Teddy Riley, Kevin "She'kspere" Briggs, Richard Marx, Veit Renn, Babyface, and Guy Roche.

After several delays due to legal battles, No Strings Attached was met with generally favorable reviews from music critics. The album debuted atop the U.S. Billboard 200 with first-week sales of 2.4 million copies, setting the record for one-week sales in the country; the group still holds the record today. Four singles were released from the album. Its lead single "Bye Bye Bye" is credited with creating the hype for the album's eventual landmark success.
