Breathe (Taylor Swift song)

"Breathe" is a song by Taylor Swift featuring Colbie Caillat from Swift's second studio album, Fearless (2008). Swift wrote the song with Caillat and produced it with Nathan Chapman. A pop rock ballad, "Breathe" incorporates strummed acoustic instruments and a string section. The lyrics are about heartbreak from losing a close friend. Big Machine Records released the track onto Rhapsody on October 21, 2008. Music critics found "Breathe" a sentimental song with resonant lyrics, but some deemed it insubstantial. The song was nominated for Best Pop Collaboration with Vocals at the 52nd Annual Grammy Awards in 2010.

"Breathe" peaked at number 87 on the US Billboard Hot 100 and was certified gold by the Recording Industry Association of America. Swift performed the song live on August 18, 2018, in Miami Gardens, Florida, for the Reputation Stadium Tour. After a 2019 dispute regarding the ownership of Swift's back catalog, she re-recorded "Breathe" with Caillat and released it as "Breathe (Taylor's Version)" as part of Fearless (Taylor's Version), the re-recording of Fearless, in 2021. "Breathe (Taylor's Version)" charted on the Canadian Hot 100 and the Billboard Global 200.
