Theodore Roosevelt, a 1955 gross ton passenger steamship, was built at Toledo, Ohio, in 1906. After some twelve years of commercial employment carrying passengers and cargo on southern Lake Michigan, she was purchased by the Navy in the spring of 1918 and converted to a troopship at a Great Lakes shipyard. USS Theodore Roosevelt (ID # 1478) apparently left the Lakes late in 1918 and was assigned to duty as a "cross channel transport", presumably operating between England and France.

Sold at the beginning of July 1919, Theodore Roosevelt reentered Great Lakes passenger service on Lake Erie, where she operated until 1926. She was then modified and went back to Lake Michigan, but was also used in the Detroit area and perhaps elsewhere during the next two decades. Laid up in about 1945, Theodore Roosevelt was sold for scrapping in 1950.
