Oakland is the largest city and the county seat of Alameda County, California. A major West Coast port, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the Bay Area, and the eighth most populated city in California. With a population of 440,646 as of 2020, it serves as a trade center: the Port of Oakland is the busiest port in Northern California, and the fifth busiest in the United States of America. An act to incorporate the city was passed on May 4, 1852, and incorporation was later approved on March 25, 1854. Oakland is a charter city.Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. In the late 18th century, it became part of a large rancho grant in the colony of New Spain. Its land served as a resource when its hillside oak and redwood timber were logged to build San Francisco. The fertile flatland soils helped it become a prolific agricultural region. In the late 1860s, Oakland was selected as the western terminal of the Transcontinental Railroad. Following the 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the population, increasing its housing stock, and improving its infrastructure. It continued to grow in the 20th century with its busy port, shipyards, and a thriving automobile manufacturing industry.

Downtown Oakland is the central business district of Oakland, California, United States; roughly bounded by both the Oakland Estuary and Interstate 880 on the southwest, Interstate 980 on the northwest, Grand Avenue on the northeast, and Lake Merritt on the east. The Downtown area is sometimes expanded to refer to the industrial and residential Jack London Square and Jack London warehouse district areas, the Lakeside Apartments District, which are a largely residential neighborhood on the west side of Lake Merritt, the Civic Center district, Chinatown, and the south end of Oakland's Broadway Auto Row, an area along Broadway which has historically been used by car dealers and other automotive service businesses. While many consider these areas outside of downtown proper, they are generally considered more geographically proximate to Downtown Oakland than to East Oakland, North Oakland or to West Oakland and are thus sometimes associated with Downtown Oakland.
