"Unbreakable" is a song by American R&B-soul singer Alicia Keys, released by J Records on September 6, 2005 as the lead single from her live album, Unplugged (2005). Written by Keys, Kanye West, and Harold Lilly, the track features a Wurlitzer riff, and is built around a sample of Eddie Kendricks' 1977 song "Intimate Friends", written by Garry Glenn. Due to its inclusion on a live album, album producer Alex Coletti is credited with the song's production, although the beat composition was helmed by West.
