SS President Roosevelt was an ocean liner in service in the 1920s and 1930s. Originally built as a Harris-class attack transport towards the end of World War I, she entered commercial service after her completion. Having been built as Peninsula State, she was soon renamed President Pierce and then President Roosevelt. Requisitioned for service as a troopship with the US Navy during World War II, she was renamed USS Joseph T. Dickman (APA-13) and served in the Atlantic and Pacific theaters, being scrapped postwar in 1948.
