Melin Tregwynt is a woollen mill in the hamlet of Tregwynt in the parish of Granston, Pembrokeshire, Wales.
A mill has stood on this site since 1819 taking fleeces from the sheep farms of the area, carding and spinning them into woollen yarn and then weaving the yarn into cloth and blankets.
The mill today makes a line of upmarket blankets, cushions, clothing and accessories.
