"Big C" is a fight song of the University of California, Berkeley. It was composed in 1913 by Harold P. Williams, with lyrics by Norman Loyall McLaren. It was written to commemorate the construction of the large concrete "C" in 1905 on the "rugged Eastern foothills" of the Berkeley campus. The song was the winning entry in the Daily Californian school song competition in 1913. Arrangements of the tune are used by other schools in the University of California system.
