The name of the village is believed to come from the Cornish words "Porth" (harbour) and "gwynn" (white).
Its earliest mention is when Laurence de Porquin took his name from the village in 1327.

During the medieval period, boats from Port Quin often sailed to Wales trading coal, manure, antimony, lead and building ashlar.
The cove was from where granite from Lundy Island - used to build the tower of the parish church at St Endellion - was unloaded.
The local economy was based primarily upon the pilchard season that operated from August to December.
Fresh catches were placed in several large drying sheds in the village before being transported for sale.
Farming and small tin mines were also important sources of revenue.

The size of the remaining fish cellars indicates that Port Quin was once a prosperous village.
But by 1841 it was entering decline, a census recorded it had a population of 94 people and 23 houses.
The community was slowly moving to neighbouring villages because of poor pilchard and herring seasons and the closure of local mines.
Many emigrated (via Padstow) to Canada.
As Port Quin dwindled to the size of a hamlet, its demise gave rise to the local legend of disaster at sea.
It states that one Sunday - breaking the Sabbath - all the men of village put to sea but were lost in a great storm that destroyed the entire fishing fleet.

In February 1700 the East Indian ship Thornton was wrecked at Port Quin.

On the south-west side of the inlet is Doyden Point, on which is situated Doyden Castle, a castellated folly built about 1830 by a Samuel Symons, a late Regency bon viveur from Wadebridge.
