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.

The album charted on the Billboard R&B Top 20. It features a ten-minute title track, largely consisting of an improvised solo by guitarist Eddie Hazel. In 2009, Pitchfork named it the 17th best album of the 1970s. In 2020, Rolling Stone ranked Maggot Brain the 136th greatest album of all time in its updated list.
