"Burn" is a song by American R&B singer Usher, which he wrote with American songwriters Jermaine Dupri, Bryan-Michael Cox. The song was produced by Dupri and Cox for Usher's fourth studio album, Confessions (2004). "Burn" is about breakup in a relationship, and the public referred to it as an allusion to Usher's personal struggles. Originally planned as the album's lead single, "Burn" was pushed back after favorable responses for the song "Yeah!". "Burn" was released as the second single from the album on March 21, 2004.

"Burn" topped various charts around the world, including the Billboard Hot 100 for eight non-consecutive weeks; it succeeded "Yeah!" at number one. Both singles gave Usher nineteen consecutive weeks at the top spot, longer than any solo artist of the Hot 100 era. "Burn" was certified platinum in Australia and United States, and gold in New Zealand. The song was well received by critics and garnered award nominations. In 2009 it was named the 21st most successful song of the 2000s, on the Billboard Hot 100 Songs of the Decade. This song won the 2005 Kids' Choice Award for Favorite Song.

When Usher planned to make a new record after his third album, 8701 (2001), he decided to not branch out that much with musical collaborators and continue building music with his previous producers. Usher again enlisted record-producer Jermaine Dupri, who had collaborated on his two previous albums, along with The Neptunes, R. Kelly, among others to work on his fourth studio album Confessions (2004). Dupri contacted his frequent collaborator Bryan-Michael Cox, who had also made hits like the 2001 single "U Got It Bad" for Usher. During the early session for the album, Dupri and Cox talked about a situation which later became "Burn". At that time, Usher's two-year relationship with TLC's Chilli was flaming out. They said, "Yo, you gotta let that burn ... That's a song right there", and started writing.
