Caspar Brötzmann (born 1962 in Germany) is an electric guitar player.

In Caspar Brötzmann Massaker, Caspar Brötzmann is joined by his friends Eduardo Delgado Lopez (bass / vocals), Danny Arnold Lommen (drums) and, occasionally, by FM Einheit ("street salvage" percussionist). While Brötzmann typically performs with the power trio lineup of Massaker, with guitar, bass guitar and drum set, he only uses rock and roll and heavy metal music as a basis for his music. Brötzmann's technique has been praised: "…his attack on the instrument — explosive, obstreperous, large scale, textural, timbral — asserts the material facts of string-pickup-amplifier more bluntly than anyone else currently involved in rock".

Brötzmann has been compared to Jimi Hendrix (perhaps an inevitable comparison for an adventurous left-handed Fender Stratocaster player prone to extreme loudness and deft manipulation of audio feedback), and to Edgard Varèse, who, like Brötzmann, demonstrated a keen awareness for the importance of sound as well as properly notated music.

Brötzmann's father, Peter Brötzmann, is a free jazz saxophone player. They have recorded a duo album, Last Home.
