Philip Labonte (lah-bon-tee) is an American musician from Massachusetts, best known as the lead singer of the metalcore band All That Remains.

Labonte's first band was formed in the mid-nineties by the name of Perpetual Doom. The band played death metal and its members were teenagers at the time. The original vocalist of Perpetual Doom was Scott Estes. Labonte, however, took over the vocal position and also played the guitar. Other members included Ken Robert (vocals, guitar), Bill Brault (bass), and Steve Gonsalves (drums). Perpetual Doom released a seven track demo in 1995 called "Sorrow's End".

Labonte left Perpetual Doom, however, to be the lead vocalist for Shadows Fall. Labonte did not play guitar for this band like he did in Perpetual Doom, and was Shadows Fall's first vocalist, completing their first ever lineup. The band's debut record, Somber Eyes to the Sky, was released in 1997 through Lifeless Records, a label owned by Shadows Fall guitarist Matt Bachand. Labonte left Shadows Fall and was replaced by current vocalist Brian Fair, leaving Somber Eyes To The Sky as the only Shadows Fall record with Labonte on vocals.

In 1998, Labonte formed All That Remains as a side project. After leaving Shadows Fall, All That Remains became his main priority. Their debut record, Behind Silence and Solitude, was released in 2002 through Prosthetic Records/Razor & Tie. A short time later, Labonte tried out for Killswitch Engage after the departure of their vocalist, Jesse Leach. Although he lost the audition to current vocalist Howard Jones, the band told him he was a close second. In Killswitch Engage's DVD "(Set This) World Ablaze", Labonte states that Jones is and always will be a better singer than him.

Labonte currently takes singing lessons from Melissa Cross and released All That Remains' most recent record, The Fall of Ideals, in the summer of 2006.
