New Quay is a small once industrial abandoned hamlet and intensive mining port on the steep, winding banks of the River Tamar in Devon.

Since July 2006 New Quay is within the World Heritage Site that is the Cornwall and West Devon Mining Landscape.

[8] It to an extent benefited from the short but major engineering feat of the Tavistock Canal, forming a junction with the Tamar at Morwellham quay, completed in June 1817 with a tunnel of 1.75 miles (2.82 km) altogether built at an expense of £68,000 (equivalent to £6,289,000 in 2023) being in engineering and in export of ores a remarkable achievement before its decline in the 1860s.

[4] Since the village was abandoned in the early 20th century it became overgrown and large cut masonry stones from the quay were stolen.

In 2008 work was begun to halt New Quay's further destruction: many of the buildings were stabilised and repaired and much of the undergrowth was cut back.
