Lawrence & Foulks was a 19th-century American shipbuilding company based in New York. Established in the early 1850s, the company built 144 vessels of all types over the course of some fifty years, but is best known for its production of high-speed wooden-hulled steamboats and steamships. Notable vessels built by the company include the record-breaking Hudson River steamboat Chauncey Vibbard, the luxury Long Island Sound steamer Commonwealth, and the fast oceangoing steamships—later U.S. Navy gunboats—Bienville and De Soto. In addition to the domestic market, the company also built ships for service as far afield as South America and China.
