Haleakala was a steam cargo ship built in 1919 by Long Beach Shipbuilding Company of Long Beach 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. The vessel was first employed in the Pacific trade before being briefly laid up. She was reactivated in 1922 and entered the South American trade connecting the ports of Argentina and Brazil with a variety of ports in the Northeastern United States. In September 1926 while on one of her regular trips, she disappeared without a trace, possibly foundering in the hurricane with the loss of all hands.
