Kempstone Hill is a landform in Aberdeenshire, Scotland within the Mounth Range of the Grampian Mountains. The peak elevation of this mountain is 132 metres above mean sea level. This hill has been posited by Gabriel Jacques Surenne, Archibald Watt and C.Michael Hogan as the location for the noted Battle of Mons Graupius between the Romans and the indigenous Caledonians. The major Roman Camp of Raedykes is situated about three kilometres to the west. From Kempstone Hill there are fine views to the North Sea facing east and slightly to the north of Muchalls Castle. There is a UK trigpoint installation on Kempstone Hill.
Kempstone Hill is situated approximately 2.3 kilometers to the north of Stonehaven; surface runoff and drainage from the northern and eastern slopes of Kempstone Hill flow north to the Burn of Muchalls. Surface runoff from the south and west flanks flow to the Burn of Monboys, a very slightly alkaline stream These low pH levels (compared to other area streams) may be caused in part by the peat drainage from the moorland on Meikle Carewe Hill and Curlethney Hill. To the south the terrain falls rather sharply descending to Limpet Burn, which watercourse flows to the North Sea. The riparian woodland along Limpet Burn has been classified as high value habitat by the Aberdeenshire Council.
