St Lawrence is a village and former civil parish, now in the parish of Ventnor, on the south coast of the Isle of Wight, in southern England. It is located to the west of the town of Ventnor, in the Undercliff, which is subject to landslips. The Undercliff lies between the original high cliff and the sea, formed over thousands of years, since the last Ice Age, from accumulated landslips. Several rocky coves can be accessed from the coastal path, which affords fine views of some prominent Victorian villas, set in a wooded landscape below the great rock wall of the original sea cliff: Woody Bay, Mount Bay and Orchard Bay. The area of the parish was around 329 acres (133 ha) in size. In 1931 the parish had a population of 329. On 1 April 1933 the parish was abolished and merged with Ventnor.

Ventnor is a seaside resort town and civil parish established in the Victorian era on the southeast coast of the Isle of Wight, England, eleven miles (18 km) from Newport.
