Saltwick Bay is a north-east facing bay approximately one mile to the east of Whitby, on the east coast of North Yorkshire, England. The bay contains the Saltwick Nab alum quarries, listed under the Ancient Monuments and Archaeological Areas Act 1979.

The bay is part of the Saltwick Formation and known for its collections of fossils. The SS Rohilla hospital ship sank in the bay in 1914, and the fishing trawler Admiral Von Tromp was shipwrecked there in 1976. The bay is accessible through Whitby Holiday Park.
