Bullet in the Head is a song by American rap metal band Rage Against the Machine, released as the second single from their 1992 eponymous debut album. A fan favorite and one of the album's heaviest tracks, "Bullet in the Head" refers to the band's belief that the government uses media to control the population, drawing comparisons between typical residences and Alcatraz. The track was transferred intact from the band's demo, also titled Rage Against the Machine.

As well as one of the band's most well known riffs, the song features many innovative guitar techniques by Tom Morello. These heavily use a DigiTech Whammy pitch shifter and wah-wah pedal. In the verses, Morello picks the open D and G strings on his guitar with the DigiTech Whammy in the open (furthest) position to raise the pitch by two octaves. This creates a 'sampling' sound. Not as often heard is an unusual sound believed to be Morello picking a natural harmonic on his guitar and then raising the pitch with the Whammy pitch shifter. The band debuted "Bullet in the Head" at their first public performance at California State University, Northridge in The Quad on October 23, 1991.

Both front and back images for the single's artwork were by the French photographer Marc Riboud.

"Bullet in the Head" is mentioned in the lyrics to Pennywise's "I Won't Have It", from their 1995 album About Time. In the booklet of the album, Zack de la Rocha's name is also mentioned next to the "Bullet in the Head" part.
