The Port of Oakland is a major container ship facility located in Oakland, California, in the San Francisco Bay. It was the first major port on the Pacific Coast of the United States to build terminals for container ships. As of 2022, it was the eighth busiest container port in the United States, behind the ports of Los Angeles, New York/New Jersey, Long Beach, Savannah, Houston, Virginia, and Seattle/Tacoma. Development of an intermodal container handling system in 2002 after over a decade of planning and construction positions the Port of Oakland for further expansion of the West Coast freight market share. In 2019 it ranked 8th in the United States in the category of containers.

Oakland is the most populous city in and the county seat of Alameda County, California, United States. A major West Coast port, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, and the third-largest city overall in the Bay Area.

A charter city, Oakland was incorporated on May 4, 1852, in the wake of the state's increasing population due to the California gold rush.
