Portreath is a village, civil parish and fishing port in the Kerrier district of Cornwall, England, UK. The village is spread along a stream valley away from the beach, clinging to both slopes, towards the main centre around the harbour and parade of shops, about 300 metres from the seafront.

During the American Revolutionary War, lieutenant-colonel of the North Devon militia, Francis Basset, commanded local miners to fortify the port, which helped counter a Franco-Spanish invasion fleet gathered as part of the European theatre of the war.

However, it was considered the centre of the industrial age because it was important as a centre for copper and tin and as the nearest village to the RAF station on the hill to the north.

Further up the valley are small clothing factory outlets and to the south, the significant remains of the old cable-worked incline used by the Hayle Railway in the 19th and early 20th centuries to descend to the quayside. The old mineral tramway between Portreath on the North Coast and Devoran on the South, has been opened as a public footpath and cycle track.

The Small Village is home to one very well regarded primary school, Portreath Community Primary School which has an excellent reputation. Nearly all of the schools intake is from the village itself.
