Great Whernside is a fell in the Yorkshire Dales, England, not to be confused with Whernside, some to the west. Its summit is the highest point of the eastern flank of Wharfedale above Kettlewell. Great Whernside forms the watershed between Wharfedale and Nidderdale, and is on the boundary between the Yorkshire Dales National Park and Nidderdale Area of Outstanding Natural Beauty. The River Nidd rises on the eastern slopes of Great Whernside, above Angram Reservoir.
