Rinsey is a hamlet in Cornwall, England, UK. It is located off the main A394 road between Helston and Penzance in the civil parish of Breage. The nearby hamlet of Rinsey Croft is located 1 km to the north-east. The nearby cliffs and beach are owned and managed by the National Trust and part of Rinsey East Cliff is designated as the Porthcew Site of Special Scientific Interest (SSSI) for its geological interest. The South West Coast Path passes through the property.
Rinsey lies within the Cornwall Area of Outstanding Natural Beauty (AONB). Almost a third of Cornwall has AONB designation, with the same status and protection as a National Park.
Wheal Prosper, (grid reference SW593270) on Rinsey East Cliff, started operating in 1860 possibly as an extension of Wheal Trewarvas mine, 800m to the east on Trewarvas Cliff (grid reference SW600265). The mine is on the southern end of the Tregonning granite within the Wendron Mining District. By the time Prosper closed in 1866 it had produced mostly tin and a little copper from the Porthcew lode. The prominent house on Rinsey Head was once the mine's count house (offices). In 1990 part of Rinsey Cliff was notified as the Porthcew SSSI for the mineral assemblage caused by the granite contact zone on the Upper Devonian Mylor Slates. The contact zone is also a Geological Conservation Review site of national importance.
