Bob Log III (born November 21, 1969) is an American slide guitar one-man band based in Tucson, Arizona, and Melbourne, Australia. 

During performances, he plays old Silvertone archtop guitars, wears a full body human cannonball suit, and a helmet wired to a telephone receiver, which allows him to devote his hands and feet to guitar and drums. 

His show has been described as a blues punk guitar dance party.
