North Kesteven is a local government district in the East Midlands region of England. Just over 100 miles (160 km) north of London, it is east of Nottingham and south of Lincoln. North Kesteven is one of seven districts in Lincolnshire, England and is in the centre of the county. Its council, North Kesteven District Council, is based in Sleaford in the former offices of Kesteven County Council.
The district was formed on 1 April 1974, under the Local Government Act 1972. It was a merger of the previous Urban District of Sleaford, along with East Kesteven Rural District and North Kesteven Rural District, all from the former administrative county of Kesteven.
