Whernside is a mountain in the Yorkshire Dales in Northern England. It is the highest of the Yorkshire Three Peaks, the other two being Ingleborough and Pen-y-ghent. It is the highest point in the ceremonial county of North Yorkshire and the historic West Riding of Yorkshire with the summit lying on the county boundary with Cumbria. It is the fifteenth most prominent hill in England.

The Yorkshire Dales are a series of valleys, or dales, in the Pennines, an upland range in England. They are mostly located in the ceremonial county of North Yorkshire, but extend into Cumbria and Lancashire; they were historically entirely within Yorkshire. The majority of the dales are within the Yorkshire Dales National Park, created in 1954. The exception is the area around Nidderdale, which forms the separate Nidderdale Area of Outstanding Natural Beauty.
