Maenporth (Cornish: Meyn Borth, meaning stones cove) is a cove and beach in west Cornwall, England, United Kingdom. It is situated approximately two miles (3 km) south-southwest of Falmouth on the estuary of the River Fal.
The beach shelves gently and at low water leaves an area of shallow water that is safe for swimming. The beach has facilities for launching boats, scuba diving and sea kayaking.
