San Leandro is a city in Alameda County, California, on the eastern shore of San Francisco Bay, set between Oakland to the northwest and Hayward to the southeast. Its population was 91,008 at the 2020 census. San Leandro is one of the East Bay's older cities, with a history that long predates the region's suburban boom and roots in agriculture and manufacturing. The city's economy grew through the 20th century around industry and food processing. San Leandro became known for its factories and food plants — including chocolate and sausage production — and at one point carried the nickname "Sausage Capital of California." That manufacturing heritage remains visible in the city's industrial districts along the bay and the freeway corridors, even as the economy has diversified into health care, logistics, and services. San Leandro's geography is a key asset. It stretches from the bay shoreline, with its marina and regional shoreline parks, eastward across flat residential neighborhoods toward the East Bay hills. Two BART stations — San Leandro and Bay Fair — give the city direct rail access to Oakland, San Francisco, and the rest of the region, and Interstates 880 and 580 frame its edges. The city's community life is strong and rooted. The annual Cherry Festival celebrates San Leandro's agricultural past, the Sausage and Suds Music Festival carries on its food-industry identity, and farmers markets and neighborhood parks anchor local life. For residents, San Leandro offers the practicality of a centrally located East Bay city — diverse housing, transit access, and a genuine small-town civic culture — at the center of the Bay Area's urban core.
