SS Palo Alto was a concrete ship built as a tanker at the end of World War I. She was built by the San Francisco Shipbuilding Company at the U.S. Naval Shipyard in Oakland, California. She was launched on 29 May 1919, too late to see service in the war. She was mothballed in Oakland until 1929, when she was bought by the Seacliff Amusement Corporation and towed to Seacliff State Beach in Aptos, California, USA.
