Quarrington is a village and former civil parish, now part of the civil parish of Sleaford, in the North Kesteven district of Lincolnshire, a non-metropolitan county in the East Midlands of England. The old village and its church lie approximately 1.2 miles (2 km) south-west from the centre of Sleaford, the nearest market town, but suburban housing developments at New Quarrington and Quarrington Hill effectively link the two settlements. Bypassed by the A15, it is connected to Lincoln and Peterborough, as well as Newark and King's Lynn (via the A17). At the 2011 census, Quarrington and Mareham ward, which incorporates most of the settlement, had an estimated population of 7,046.
