The UCLA–USC rivalry is the American collegiate athletics rivalry between the UCLA Bruins sports teams of the University of California, Los Angeles (UCLA) and USC Trojans teams of the University of Southern California (USC).
Both universities are located in Los Angeles and are members of the Pac-12 Conference, and both will move together to the Big Ten Conference in 2024. The rivalry between the two is among the more unusual in National Collegiate Athletic Association (NCAA) Division I sports, because the campuses are only apart, and both are located within the same megacity.
UCLA teams have won the second-most NCAA Division I-sanctioned team championships, while USC has the third-most. Only Stanford University, a fellow Pac-12 member also located in California, has more than either UCLA or USC.
USC is recognized as consistently being one of the top football programs in the nation, while UCLA is recognized as consistently being one of the top basketball programs in the nation. However, a somewhat rare confluence of events occurred in 1954, which began with USC in its last of only two Final Four appearances in the 1954 NCAA basketball tournament and ended with UCLA winning its only non-NCAA Football National Championship.
Both schools also are successful in many "non-revenue" or "Olympic" sports. Both have had success in track and field, water polo, tennis, volleyball, and golf. As of 2023, USC has won 26 NCAA championships in men's outdoor track and field, 21 in men's tennis, and 12 in baseball, the most of any school in each respective sport. Likewise, UCLA has won 20 NCAA championships in men's volleyball and 12 in softball, also the most of any school in those sports. Both also are the only schools to have won official NCAA championships in beach volleyball, with USC winning 5 and UCLA 2.
As of January 2022, UCLA ranked second overall in NCAA team championships, with 119, behind Stanford, with 128. They also rank second in men's NCAA team championships with 76, and second (behind Stanford) in women's NCAA team championships with 43.
