Brian Patrick Carroll (born May 13, 1969), better known by his stage name Buckethead, is an American guitarist and multi-instrumentalist who has worked within many genres of music. He has released 114 studio albums, four special releases and one EP. He has also performed on more than 50 other albums by other artists. His music spans such diverse areas as progressive metal, funk, blues, jazz, bluegrass, ambient, and avant-garde music.

Buckethead is famous for wearing a KFC bucket on his head, emblazoned with an orange bumper sticker reading FUNERAL in capital black block letters, and an expressionless plain white mask which, according to Buckethead, was inspired by his seeing Halloween 4: The Return of Michael Myers. At one point, he changed to a plain white bucket that no longer bore the KFC logo, but subsequently reverted to his trademark KFC bucket. He also incorporates nunchaku and robot dancing into his stage performances.
