Carnethy Hill, the second highest of the Pentland Hills, is a hill 3 miles (5 km) north-west of Penicuik, Scotland.
It lends its name to the Carnethy 5 hill race held annually since 1971, and the Carnethy Hill Running Club.[1] Loganlea Reservoir lies on the northwest flank of the hill.
Carnethy is probably etymologically a Cumbric name. The main suggestion in past scholarship is that it is cognate with Welsh carneddau, 'cairns'.[2]
