Grindon is a village and civil parish in the borough of Stockton-on-Tees, in County Durham, England. It is situated between Sedgefield and Stockton-on-Tees, near to Thorpe Larches. The place name of "Grindon" is derived from the word 'dun', which meant hill. Grindon is situated in the Upland Fells, formed of Carboniferous millstone grit. "The alternating strata of harder and softer rocks give a stepped profile to many dale sides and distinctive flat-topped summits to the higher fells."
