San Leandro, California

San Leandro is a city in Alameda County, California, United States, in the East Bay of the San Francisco Bay Area, between Oakland to the northwest and Ashland, Castro Valley and Hayward to the southeast. Its name is Spanish for Saint Leander and refers to Leander of Seville, a sixth century Spanish bishop. Europeans first visited the area on 20 March 1772, and the land later belonged to the Mexican grants of Rancho San Leandro and Rancho San Antonio. A townsite was laid out from 1855 by John B. Ward and William Heath Davis, sons-in-law of the grantee, and San Leandro served briefly as the Alameda County seat until the 1868 Hayward Fault earthquake destroyed the courthouse. It has a long-standing Portuguese American community that dates from the 1880s, and by the 2010 census Asian Americans had become the largest group. The population was 91,008 at the 2020 census.
