San Francisco (city) San Francisco is a coastal city on the San Francisco Peninsula in California, United States, known for its dense urban core, hilly topography, and cultural influence.

San Francisco's modern history began with the Presidio of San Francisco and the founding of Mission San Francisco de Asís in 1776, during the Spanish Empire's expansion along the El Camino Real.
