Smelthouses is a hamlet in Nidderdale in North Yorkshire, England. It lies about 2.3 miles (4 km) south-east of Pateley Bridge, on either side of Fell Beck, a small tributary of the River Nidd. Fell Beck here forms the boundary between the civil parishes of Hartwith cum Winsley and High and Low Bishopside, so that the settlement is divided between the two parishes.
