Glenn Branca (October 6, 1948, Harrisburg, Pennsylvania, USA) is an American composer who studied performing arts at Emerson College in Boston. After graduation he formed two bands, in 1977 with Jeffrey Lohn, and later The Static.

In the eighties his compositions for the Glenn Branca Ensemble included the several symphonies for which he is best known. Branca's compositions center around multiple guitars - four or more, heavily amplified - augmented by a rock-based rhythm section of drums and bass. In later works, the composer began adding other instruments, including mallet guitar, keyboards, and occasionally a second drummer. Branca's minimalist compositions frequently require unusual guitar tunings.
