"Scar Tissue" is the first single from the American rock band Red Hot Chili Peppers' seventh studio album Californication, released in 1999. It is one of their most successful songs, spending a then-record 16 consecutive weeks on top of the Billboard Hot Modern Rock Tracks chart, as well as 10 weeks at the top of the Billboard Mainstream Rock Tracks chart and reached number 8 on Billboard Hot 100 Airplay. It peaked at number 9 on the Billboard Hot 100. In the UK, the song reached number 15 on the UK Singles Chart. It won a Grammy Award for Best Rock Song in 2000. The song is notable for its mellow intro guitar riff and for its slide guitar solos throughout. Guitar World placed the guitar solo 63rd in its list of the "100 Greatest Guitar Solos".

"Scar Tissue" is considered to be representative of the new, more melodic rock sound the band experimented with on Californication (in contrast to the psychedelic One Hot Minute, and dry funk of Blood Sugar Sex Magik).

In 2004 Anthony Kiedis published Scar Tissue. Co-written by Larry Sloman, it was an autobiography with the principal theme of sex, drugs and rock-'n-roll. In the book he talks about the consequences of drugs (especially heroin) and in which way this can destroy somebody's life.
