"Lucy Doesn't Love You" is a song by American band Ivy for their third studio album, Long Distance (2000). Lead singer Dominique Durand wrote the song with band members Adam Schlesinger and Andy Chase, who both produced it. In 2000, it was chosen as the album's lead single in Japan and distributed via Chase's Unfiltered Records label. Musically, the song was described as a melodic, horn-led trip hop and synth-pop track. Its lyrics find a woman confronting a lovestruck man who desires a different woman, named Lucy, who is not in love with him. American musician Eric Matthews performs trumpet on "Lucy Doesn't Love You", alongside Paco member Michael Hampton, who contributes to the song's instrumentation.
