Northamptonshire (/nɔːˈθæmptənʃɪə, -ʃə/;[4] abbreviated Northants.), archaically known as the County of Northampton, is a county in the East Midlands of England. In 2015 it had a population of 723,000. The county is administered by Northamptonshire County Council and by seven non-metropolitan district councils. It is known as "The Rose of the Shires".
Covering an area of 2,364 square kilometres (913 sq mi), Northamptonshire is landlocked between eight other counties: Warwickshire to the west, Leicestershire and Rutland to the north, Cambridgeshire to the east, Bedfordshire to the south-east, Buckinghamshire to the south, Oxfordshire to the south-west and Lincolnshire to the north-east – England's shortest administrative county boundary at 20 yards (19 metres), although this was not the case with the historic county boundary.[5] Northamptonshire is the southernmost county in the East Midlands region.
Apart from the county town of Northampton, other major population centres include Kettering, Corby, Wellingborough, Rushden and Daventry. Northamptonshire's county flower is the cowslip.[6] The city of Peterborough was also part of the county until the creation of the Soke of Peterborough.
