Leighton Road Cutting () is a 0.6 hectare geological Site of Special Scientific Interest between East Cranmore and Cloford in Somerset, notified in 1984. It is a Geological Conservation Review site Leighton Road Cutting provides exposure of a series of early Jurassic limestones, of Lower Lias age, which are the only known outcrops of these particular rocks to occur in a normal horizontally-bedded sequence in the Mendips. The discovery of the Leighton Road Cutting sections enabled geologists to understand how the fissure infills seen widely throughout the Mendips had been formed.
