Wensleydale is a valley in North Yorkshire, England. It is one of the Yorkshire Dales, which are part of the Pennines. The dale is named after the village of Wensley, formerly the valley's market town. The principal river of the valley is the Ure, which is the source of the alternative name Yoredale. The majority of the dale is within the Yorkshire Dales National Park; the part below East Witton is within the national landscape of Nidderdale.

The Nidderdale National Landscape is an Area of Outstanding Natural Beauty in North Yorkshire, England, bordering the Yorkshire Dales National Park to the east and south. It comprises most of Nidderdale itself, part of lower Wharfedale, the Washburn valley and part of lower Wensleydale, including Jervaulx Abbey and the side valleys west of the River Ure. It covers a total area of 233 square miles (600 km2). The highest point in the Nidderdale AONB is Great Whernside, 704 metres (2,310 ft) above sea level, on the border with the Yorkshire Dales National Park.
