The 1920 college football season had no clear-cut champion, with the Official NCAA Division I Football Records Book listing California, Georgia, Harvard, Notre Dame, and Princeton as national champions. Only California and Princeton claim national championships for the 1920 season. Andy Smith's Pacific Coast Conference champion California "Wonder Team" was the first national champion from the Pacific Coast. Princeton and Harvard were undefeated and with one tie to each other. Notre Dame was led by its first Walter Camp All-American, George Gipp, who died before the year was over.

The 1920 California Golden Bears football team was an American football team that represented the University of California, Berkeley as a member of the Pacific Coast Conference (PCC) during the 1920 college football season. In their fifth year under head coach Andy Smith, the team compiled a 9–0 record, shut out seven of nine opponents, won the PCC championship, defeated Ohio State in the 1921 Rose Bowl, and outscored its opponents by a total of 510 to 14.
