Central California is generally thought of as the middle third of theU.S. state ofCalifornia, north ofSouthern California (which includesLos Angeles andSan Diego) and south ofNorthern California (which includesSan Francisco andSan Jose). It includes the northern portion of theSan Joaquin Valley (which itself is the southern portion of theCentral Valley, beginning at theSacramento–San Joaquin River Delta), part of theCentral Coast, the central hills of theCalifornia Coast Ranges and the foothills and mountain areas of thecentral Sierra Nevada.
Central California is considered to be west of the crest of theSierra Nevada. East of the Sierra isEastern California.
