Great Dun Fell is the second-highest hill in the Pennine range, United Kingdom, lying two miles south along the watershed from Cross Fell, its higher neighbour. Together with its smaller twin, Little Dun Fell, it forms a stepping-stone for the Pennine Way on its long climb up from Dufton.

The fell would be just another Pennine summit were it not for a remarkable construction on the summit; a radar station that can be seen from as far away as the Lake District with the naked eye. Operated by NATS the station is a key part of the Air Traffic Control system for the North Atlantic area. A dome containing an SSR, various towers and fencing crown the summit. Alfred Wainwright abhors this radar station in his book "Pennine Way Companion".

The construction of the radar station has led to the repaving of a tarred road to the summit which in turn led to being Britain's highest road. This road is private and not open to the public.

On the 19th of August 2007 Great Dun Fell was set to be featured in an episode of the BBC's Mountain program, but was later cut out.
