North County (San Diego County) is the commonly used regional designation for the northern portion of San Diego County, California, encompassing coastal, inland, and foothill communities north of Downtown San Diego and south of the Orange County, California line.

Geography and boundaries
North County's geography spans coastal plains, the Santa Ana Mountains, and the inland valleys near the Cleveland National Forest, creating a corridor from Cardiff-by-the-Sea and Oceanside, California south to Del Mar, California and inland toward Escondido, California and Temecula, California. Its hydrology includes the San Luis Rey River, Santa Margarita River, and riparian corridors that lead to estuaries such as Batiquitos Lagoon and San Elijo Lagoon. The region's climate is shaped by the Pacific Ocean and the semi-arid influences that characterize Southern California, producing microclimates found in locations like Carlsbad, California and Poway, California.

Mexican-era land grants like Rancho Agua Hedionda and Rancho San Marcos shaped settlement patterns preceding Anglo-American development tied to the California Gold Rush migration and railroad expansion by companies such as the Atchison, Topeka and Santa Fe Railway. Twentieth-century growth accelerated with projects by developers associated with Howard Hughes enterprises, military installations like Marine Corps Base Camp Pendleton, and postwar suburbanization influenced by Levittown-era models and policies of the Federal Housing Administration.
