Portreath is a civil parish, village and fishing port on the north coast of Cornwall, England, United Kingdom. The village is about three miles (5 km) west-north-west of Redruth. The village extends along both sides of a stream valley and is centred on the harbour and beach. West of the harbour entrance and breakwater are two sandy beaches that are popular with holidaymakers, surfers and naturists.

The Cornwall National Landscape covers 958 square kilometres (370 sq mi) in Cornwall, England, United Kingdom; that is, about 27% of the total area of the county. It comprises 12 separate areas, designated under the National Parks and Access to the Countryside Act 1949 for special landscape protection. Of the areas, eleven cover stretches of coastline; the twelfth is Bodmin Moor. The areas are together treated as a single Area of Outstanding Natural Beauty (AONB): all AONBs have been rebranded as National Landscapes since November 2023. Section 85 of the Countryside and Rights of Way Act 2000 places a duty on all relevant authorities when discharging any function affecting land within an AONB to have regard to the purpose of conserving and enhancing natural beauty. Section 89 places a statutory duty on Local Planning Authorities with an AONB within their administrative area to produce a 5-year management plan.
