Dennis Brockenborough is an American musician who played trombone in The Mighty Mighty Bosstones for ten years and was an important contributor to the band's brass instrument-driven skacore sound.
Brockenborough joined the Mighty Mighty Bosstones in 1990 just before the release of the Where'd You Go? EP and the band's second album More Noise and Other Disturbances, replacing original trombonist Tim Bridwell.
