Wassaic was a steam cargo ship built in 1918-1919 by Los Angeles Shipbuilding & Dry Dock Company of San Pedro for the United States Shipping Board (USSB) as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. Wassaic remained in Shipping Board ownership until she was abandoned due to age and deterioration in 1931 or 1932.
