The Northern California Athletic Conference (NCAC) was an NCAA Division II college athletic association that sponsored American football that was founded in 1925. It disbanded in 1998 after the majority of its member schools were forced to drop football.
Shortly after World War II, the remaining members, with the exception of UC Davis, Chico State and Humboldt State, would leave for other conferences, to be replaced over the years by San Francisco State (joined in 1946), Southern Oregon (1947), Sacramento State (1953), Hayward State (1961) and Sonoma State (1966). During the 1990s, each of the universities associated with the California State system chose to disband their football teams in order to comply with Title IX, with the exception of Humboldt State, which added two women's sports to achieve compliance, Sacramento State,[1] and Cal Poly.
