The Portreath Tramroad, or alternatively the Portreath Tramway, was opened in 1815, providing a wagonway route from mines near Scorrier in Cornwall, England, to a port at Portreath. From there, it could be transported to market by coastal shipping. It was later extended to serve the Poldice mine near St Day and became known as the Poldice Tramroad, or Poldice Tramway.
It was a horse-drawn plateway and was the first railway in the county of Cornwall, starting operation in 1809.
As a technological pioneer, it soon became technically obsolescent but continued in use until about 1865. Much of the route can be discerned today, and parts can be walked or cycled.
