Collegiate club rugby (a collegiate version of rugby union) is played throughout universities in the United States of America. Unlike most university sports, collegiate club rugby is not administered by the National Collegiate Athletic Association or university athletic departments and is instead regulated by USA Rugby and club rec departments.

The University of California at Berkeley has won 22 of 27 Division I club championships since tournament play began in 1980. Full Article on Wikipedia
