The USC Trojans are the athletic teams representing the University of Southern California in Los Angeles, California. While the men’s teams are nicknamed the Trojans, the women’s athletic teams are referred to as either the Trojans or Women of Troy (the university officially approves both terms). The program participates in the Pacific-12 Conference and has won 122 team national championships, 100 of which are NCAA National Championships. USC’s cross-town rival is UCLA, with whom there is fierce athletic and scholastic competition. However, USC’s rivalry with Notre Dame predates the UCLA rivalry by three years. The Notre Dame rivalry stems mainly from the annual football game played between these two universities and is considered the greatest intersectional rivalry in college football.
