Sonoma State athletics began in 1964 with the school's first men's basketball team. Through the years, the Seawolves have had various successes including national championships in 1990 (women's soccer), 2002 (men's soccer), and 2009 (men's golf). The school's traditional colors are navy, Columbia, and white. SSU athletic teams participate in the CCAA, an association within the NCAA's Division II. The SSU Athletic Department offers nine NCCAA women's sports teams and five men's teams. Women's track and field has recently been re-added to university's program. Besides both being located in the west of California, but one in the south and the other in the north, Sonoma and Dominguez Hills have competed heavily as conference rivals in soccer.
