The Lynde Point Light or Lynde Point Lighthouse, also known as Saybrook Inner Lighthouse, is a lighthouse in Connecticut, United States, on the west side of the mouth of the Connecticut River on the Long Island Sound, Old Saybrook, Connecticut. The first light was a 35 feet (11 m) wooden tower constructed by Abisha Woodward for $2,200 and it was completed in 1803. A new lighthouse was eventually needed and a total of $7,500 was appropriated on July 7, 1838. Jonathan Scranton, Volney Pierce, and John Wilcox were contracted to build the new 65-foot (20 m) octagonal brownstone tower. It was constructed in 1838 and lit in 1839. The lighthouse was renovated in 1867 and had its keeper's house from 1833 replaced in 1858 with a Gothic Revival gambrel-roofed wood-frame house. In 1966, the house was torn down and replaced by a duplex house. The original ten lamps were replaced in 1852 with a fourth-order Fresnel lens, and with a fifth-order Fresnel lens in 1890. Lynde Point Lighthouse used whale oil until 1879 when it switched to kerosene. It was electrified in 1955 and fully automated by the United States Coast Guard in 1978. In 1990, it was added to the National Register of Historic Places and is significant for its "superior stone work in the tapering brownstone walls".
