"A Touch of Evil" is a song by British heavy metal band Judas Priest, from their 1990 album Painkiller. It is the only song on the album that was co-written by producer Chris Tsangarideswho wrote the song's guitar riff, while the rest of the song was written by the main songwriting team of Rob Halford, K.K. Downing and Glenn Tipton. Tsangarides would team up again with Tipton for songwriting eleven years later, for Judas Priest's album Demolition, released in 2001, on which the two of them wrote the songs "Subterfuge" and "Metal Messiah".
