The Stanford rugby teams of 1906 to 1917 represented Stanford University as the school's only football program during those years, replacing American football with rugby union. The school had played American football from 1892 to 1905, but in 1906, concerned with the growing levels of violence in football, Stanford and other universities changed to rugby. Stanford played twelve seasons of rugby, during which it played other college teams, club teams from the United States, Canada, and Australia, as well as the New Zealand national team and Australia national team. Despite the team's success, it became clear that other schools were not adopting rugby in large numbers, and after rival California returned to football in 1915, Stanford faced a limited number of potential opponents; and after a year of playing neither sport officially due to World War I, the school returned to American football in 1919.

Big Game is the name given to the California–Stanford football rivalry. It’s an American college football rivalry game played by the California Golden Bears football team of the University of California, Berkeley and the Stanford Cardinal football team of Stanford University. Both institutions are located in the San Francisco Bay Area. First played in 1892, it remains one of the oldest college rivalries in the United States. The game is usually played in late November or early December and its location alternates between the two universities every year. In even-numbered years, the game is played in Berkeley while odd-numbered years are played at Stanford.
