"Nobody Wants to Be Lonely" is a song by Puerto Rican singer Ricky Martin from his sixth studio album, Sound Loaded (2000). Martin re-recorded the song along with American singer Christina Aguilera in December 2000. The album version was written by Desmond Child, Victoria Shaw, and Gary Burr and produced by Child; the duet received additional production from Walter Afanasieff. The duet was released by Columbia Records on January 16, 2001, as the second single from the album. A mid-tempo pop song and power ballad with elements of flamenco and Latin music, it is about heartbreak and longing.

The Grammy Award for Best Pop Collaboration with Vocals was an honor presented at the Grammy Awards, a ceremony that was established in 1958 and originally called the Gramophone Awards, to recording artists for quality pop songs on which singers collaborate. Awards in several categories are distributed annually by the National Academy of Recording Arts and Sciences of the United States to "honor artistic achievement, technical proficiency and overall excellence in the recording industry, without regard to album sales or chart position."
