Gibraltar Point is a headland on the coast of Lincolnshire, England, 3.5 miles (5.6 km) south of Skegness, where the North Sea coast turns southwest towards Boston and enters The Wash. The point is at the southernmost point of a national nature reserve covering an area of about 4.3 km2 (1.7 sq mi) .
The reserve is owned by Lincolnshire County Council and East Lindsey District Council and is administered by the Lincolnshire Wildlife Trust. The reserve comprises two parallel ridges of sand dunes—the "east dunes" and the "west dunes"—separated by about half a kilometre (550 yards) of salt marsh; and an area on the seaward side with further salt marsh and sand, shingle and muddy beaches.
