The UC Men's Octet, sometimes termed the Cal Men’s Octet or the UC Berkeley Men’s Octet, is an eight-member male a cappella group at the University of California, Berkeley. Founded in 1948 as a member of the UC Choral Ensembles, the group's broad repertoire features several genres of music including barbershop, doo-wop, pop and alternative, and a healthy dose of Berkeley fight songs. The Octet has recorded over a dozen albums and is one of only four multiple-time champions of the International Championship of Collegiate A Cappella (ICCA)—the other three being USC's SoCal VoCals, Berklee's Pitch Slapped, and Belmont’s Pitchmen—having won the competition in both 1998 and 2000.
