The Jupiter is an American tugboat. It was built in Philadelphia in 1902 by Neafie & Levy for the Standard Oil Company of New York, and was named Socony No. 14. In 1939 it was sold to the Independent Pier Company in Philadelphia, and was renamed Jupiter. In 1949 it had an engine refit in Baltimore, and was converted from steam power to diesel. In 1999 it was retired from work and was sold to the Penn's Landing Corporation. It is maintained and preserved by the Philadelphia Ship Preservation Guild, and is used for tourism.
