The Hungry March Band is an American brass band with approximately 15-20 active musicians and performers. In performance, the group's size can vary from five to fifty: from a quintet to a large corps of musicians, dancers, baton twirlers, and hula hoopers.

HMB has a repertoire of originals and traditionals that borrows from global brass band traditions, including Balkan Gypsy music, Indian wedding bands, and New Orleans second line. The band also references punk rock; techno, hip hop; various jazz traditions, including free jazz and bop; reggae; and chance music. They cite Sun Ra, Charlie Parker, John Cage, the Shyam Brass Band, Fanfare Ciocarlia, Rebirth Brass Band, the Skatalites, Sonic Youth, Weird Al Yankovic, and Black Sabbath as influences.
