"If Looks Could Kill" is a song written by Jack Conrad and Bob Garrett, originally recorded by Pamala Stanley and later by the rock band Heart in 1985. The Heart version was released as the fifth and final single from the band's self-titled 1985 album Heart. This version is similar to early Heart tunes as it is an aggressive, hard rock number. The song is about a woman confronting a cheating lover, letting him know that "if looks could kill / you'd be lying on the floor".
