North Witham

North Witham is a small village and nominally a civil parish in South Kesteven, Lincolnshire, England. The village is located along the upper course of the River Witham 1.5 miles downstream (north) of South Witham, and approximately 9 miles (14 km) south from the nearest major town, Grantham. It has an estimated population of 143 in around 72 households, at a density of 0.1/hectare.

The current civil parish of Colsterworth includes the hamlet of Lobthorpe. Nearby villages include Gunby, Colsterworth and Stainby.

The village is perhaps best known for its links with Isaac Newton, who is known to have lived nearby and visited the village on numerous occasions and made carvings in the wall of the church porch, and for the presence of nearby RAF North Witham.
