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.

United States Lines was the trade name of an organization of the United States Shipping Board (USSB), Emergency Fleet Corporation (EFC) created to operate German liners seized by the United States in 1917. The ships were owned by the USSB and all finances of the line were controlled by the EFC. Among the notable ships of this period was Leviathan, a contender for largest ship in the world for a time.
