Balboa Fun Zone is the third studio album by the American punk rock band the Adolescents, released in 1988 on Triple X Records. Titled after the Balboa Fun Zone amusement area of Balboa Peninsula, Newport Beach, it is the band's only album recorded without singer Tony Brandenburg, who had left the group the prior year. Electing not to replace him, guitarist Rikk Agnew and bassist Steve Soto alternated lead vocals on Balboa Fun Zone. The album also features the return of original Adolescents guitarist Frank Agnew (Rikk Agnew's younger brother), who had been absent from their prior album, 1987's Brats in Battalions. Balboa Fun Zone is also the final Adolescents studio album to include Rikk Agnew and drummer Sandy Hanson.
