"I'm Alive" is a song co-written and recorded by American country music singer Kenny Chesney. He wrote the song with Dean Dillon and Mark Tamburino, and it was first recorded by Willie Nelson on his album Moment of Forever, which Chesney also produced. Chesney himself later recorded it (as a duet with Dave Matthews) on his 2008 album Lucky Old Sun. This version later appeared on his 2009 Greatest Hits II album, from which it was released to radio in August 2009.

Willie Nelson first recorded the song on his 2008 album Moment of Forever, which Chesney co-produced. Chesney later recorded the song as a duet with Dave Matthews on Lucky Old Sun (also released in 2008), but did not release it as a single from that album. Chesney told Country Standard Time, "It was never meant to be some kind of a message — except to maybe myself[…]It's one thing when Willie Nelson at 70 sings it, and something totally different when Dave and I do. One is from a place of really knowing; for us, it was more just the fact that we realize it." He also said that he was inspired to write the song after his divorce from actress Renée Zellweger: "Writing that song was a release. It was the best I'd felt in a long time after I wrote that song."

Chesney's version of the song is in the key of E-flat major, with a vocal range from B♭3 to F5 and a main chord progression of E♭-E♭+/G-A♭-A♭m. It is primarily accompanied by acoustic guitar, organ and light percussion.
