Freshwater Bay is a bay on the east side of the Isle of Portland, Dorset, England, south from Church Ope Cove and between the villages of Wakeham and Southwell. It forms part of the Jurassic Coast.
Freshwater Bay takes its name from a freshwater spring which emerged at the bottom of the cliff. An Admiralty pumping station was built on the clifftop in the 19th century for supplying fresh water to the naval base and to the harbour's breakwaters during their construction. Cheyne House was built for the attendant of the station.
