SS Clara Barton (Hull Number 636) was a Type EC2-S-C1 Liberty ship built by the California Shipbuilding Corporation, Terminal Island, for the United States Maritime Commission during World War II. She was named after Clara Barton, the founder of the American Red Cross. The ship was laid down on 19 July 1942, then launched on 25 August 1942. The ship survived the war only to suffer the same fate as nearly all other Liberty ships that survived did; she was scrapped in 1970.
