Shipyard Acres was an unincorporated community in Napa County, California. It lies at an elevation of 33 feet (10 m). Shipyard Acres is located 2.5 miles (4.0 km) south-southeast of Napa. This was a wartime neighborhood consisting of nearly 400 of plywood houses built to house worker families involved in the World War II effort building ships at Basalt Rock Company. It sprang up early in the war and was dismantled sometime in the mid-1950s. It was on the northwest corner of what is now Kaiser Road and Napa-Vallejo Highway. Some of the structures were moved a few miles west to the Cuttings Wharf area, resurrected, and are still in place near the marina.
