USTA Southern California is one of 17 sections of the United States Tennis Association, the national governing body for the sport of tennis. With a unique history of producing some of the greatest American players of all time, including Billie Jean King, Serena and Venus Williams, Tracy Austin, Pete Sampras, Michael Chang, Lindsey Davenport, and the Bryan brothers, the Section has become an exemplar for the sport.

The Southern California section stretches from the Central Coast to the north, to San Diego to the south, and from the Inland Empire to the east, to the Pacific Ocean to the west.
