Ventnor (/ˈvɛntnər/) is a seaside resort and civil parish established in the Victorian era on the south coast of the Isle of Wight, England. It lies underneath St Boniface Down (which, at 241 metres (791 feet), is the highest point on the Isle of Wight), and is built on steep slopes and cliffs leading down to the sea. The higher part is referred to as Upper Ventnor (although officially it is Lowtherville); the lower part, where most of the amenities are located, being known as Ventnor. Ventnor is sometimes understood as including the coastal villages of St. Lawrence to one side and Bonchurch to the other.
