Watch Hill is a small hill lying on the north-western fringe of the Lake District in England. The name Setmurthy Common is sometimes used (including by Alfred Wainwright in his book The Outlying Fells of Lakeland) to refer to the area including the highest point, with "Watch Hill" describing the area to the west of the summit. It should not be confused with another Watch Hill some 19 km to the south-west, near Whitehaven, which is only 172 m (564 ft) high. The name "The Hay" is also used when referring to the area west of the summit.
