Leicestershire is a landlocked county in the English Midlands. It takes its name from the City of Leicester, traditionally its administrative centre, although the City of Leicester unitary authority is today administered separately from the rest of Leicestershire. The county borders Nottinghamshire to the north, Lincolnshire to the north-east, Rutland to the east, Northamptonshire to the south-east, Warwickshire to the south-west, Staffordshire to the west, and Derbyshire to the north-west. The border with Warwickshire is Watling Street (the A5).

The county has a population of just under 1 million with over half the population living in Leicester's built-up area.
