"Whiplash" is a song by American heavy metal band Metallica. It was released as the first single from their debut album, Kill 'Em All, and the band's debut single overall, released on August 8, 1983.

Kill 'Em All is the debut studio album by the American heavy metal band Metallica, released on July 25, 1983, through the independent label Megaforce Records. After forming in 1981, Metallica began by playing shows in local clubs in Los Angeles. They recorded several demos to gain attention from club owners and eventually relocated to San Francisco to secure the services of bassist Cliff Burton. The group's No Life 'til Leather demo tape (1982) was noticed by Megaforce label head Jon Zazula, who signed them and provided a budget of $15,000 for recording. The album was recorded in May with producer Paul Curcio at the Music America Studios in Rochester, New York. It was originally intended to be titled Metal Up Your Ass, with cover art featuring a hand clutching a dagger emerging from a toilet bowl. Zazula convinced the band to change the name because distributors feared that releasing an album with such an offensive title and artwork would diminish its chances of commercial success.
