Wensleydale is the valley (dale) of the River Ure on the east side of the Pennines in North Yorkshire, England.
Wensleydale lies in the Yorkshire Dales National Park – one of only a few valleys in the 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 village name 'Wensley' 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.
