The Thomas S. Negus was a 19th-century two-masted Sandy Hook pilot boat, built by C. & R. Poillon shipyard in Brooklyn in 1873 for the New Jersey maritime pilots. She was built to replace the pilot boat Jane, No. 1, which sank in early 1873. She was the winner of a $1,000 prize at the Cape May Regatta in 1873. She was named for Thomas S. Negus, president of the N. J. Pilots' Commissioners. In 1897, she left the pilot service to prospect for gold during the Klondike Gold Rush.
