It is bordered by Lincolnshire to the north, Norfolk to the north-east, Suffolk to the east, Essex and Hertfordshire to the south, Northamptonshire to the west, and Bedfordshire to the south-west.

The county has an area of 3,389 km (1,309 sq mi) and had an estimated population of 906,814 in 2022. Peterborough, in the north-west, and Cambridge, in the south, are the largest settlements. The remainder of the county is rural, and contains the city of Ely in the east, Wisbech in the north-east, and St Neots and Huntingdon in the west.
