The South Ferry Company, Inc., locally referred to as South Ferry, operates a year-round public ferry service between Shelter Island and North Haven on Long Island, New York. It forms part of New York State Route 114.
The company was founded in 1830, however the first owner, Samuel G. Clark, had operated a ferry service in that location since at least 1793. Exact dates are not widely known, but the Clark family has owned the company continuously since at least 1845, making it possibly the oldest continuously family-owned ferry service in the United States. The company was added to the New York State Historic Business Preservation Registry (HBPR) in 2022.
