Wensleydale is the dale or upper valley of the River Ure on the east side of the Pennines, one of the Yorkshire Dales in North Yorkshire, England.

Wensleydale is one of only a few Yorkshire Dales not currently named after its principal river, but the older name, Yoredale, can still be seen on some maps and as the Yoredale Series of geological strata. The dale takes its name from the village of Wensley, which is a derivative of Woden’s ley, or meadow of the pagan god Woden, while the valley itself takes its name from the village which was formerly a market town.

The valley is famous for its cheese, with the main commercial production at Hawes. Most of the dale is within the Yorkshire Dales National Park. Part of lower Wensleydale, below East Witton, is within the Nidderdale Area of Outstanding Natural Beauty.
