"Eye for an Eye" is the first single by heavy metal band Soulfly, released in 1998. The song is the first track of the debut album Soulfly. However, "Eye for an Eye" is the tenth single written by Max Cavalera overall. His last single was Sepultura's "Ratamahatta" before he left the band and formed Soulfly. It has become Soulfly's trademark song, and is used at the closing of every Soulfly show since 1998.^[1]

The first Soulfly song features Fear Factory members Dino Cazares and Burton C. Bell as guests^[2] and plays fast, groovy riff lasting over 3½ minutes.
