Maggot Brain is the third studio album by the American funk rock band Funkadelic, released by Westbound Records in July 1971. It was produced by bandleader George Clinton and recorded at United Sound Systems in Detroit during late 1970 and early 1971. The album was the final LP recorded by the original Funkadelic lineup; after its release, founding members Tawl Ross (guitar), Billy Nelson (bass), and Tiki Fulwood (drums) left the band for various reasons.

Funk rock is a fusion genre that mixes elements of funk and rock. James Brown and others declared that Little Richard and his mid-1950s road band, the Upsetters, were the first to put the funk in the rock and roll beat, with a biographer stating that their music "spark[ed] the musical transition from fifties rock and roll to sixties funk".
