Norteños are the various affiliated gangs that pay tribute to Nuestra Familia while in California state and federal correctional facilities. Norteños may refer to Northern California as Norte Califas. Their biggest rivals are the Sureños from Southern California. As of 2008, the statewide north–south dividing line between Norteños and Sureños was regarded as running through the southern end of the Central Valley. The gang's membership consists primarily of Mexican Americans.
