Blackpool Mill is a 19th century flour mill in the community of Martletwy, in the Pembrokeshire Coast National Park. It sits to the west of Blackpool Bridge on the southern bank of the Eastern River Cleddau, downstream from Canaston Bridge. Built in 1813 on the site of former ironworks, the mill is a Grade-II* listed building, which is intact and contains working machinery, but has ceased commercial operation. Blackpool Mill is listed by RCAHMW as an historic place name. Several other features of the site are listed by Coflein: Blackpool bridge, a furnace, the mill leat and the wharf.
