Scar Tissue is a music group that emerged from California's electro-industrial scene in 1990. The band released three CDs on 21st Circuitry Records (distributed by Caroline Records) and appeared on numerous industrial music compilations throughout the 1990s.

Scar Tissue's music has been described as "dark electro" and is generally characterised by dense layers of percussion, ambience, and found sounds. Their live performances were notable for the use of live percussion (rare in the electronic industrial scene), and a DJ & Guitarist who played samples & noises live (including children's toys played through the guitar pickups).
