Cambridgeshire (abbreviated Cambs.) is a county in England, bordering Lincolnshire to the north, Norfolk to the north east, Suffolk to the east, Essex and Hertfordshire to the south, and Bedfordshire and Northamptonshire to the west. The city of Cambridge is the county town. Modern Cambridgeshire was formed from the historic counties of Cambridgeshire and Huntingdonshire, together with the Isle of Ely and the Soke of Peterborough; it contains most of the region known as Silicon Fen. Cambridgeshire is twinned with Kreis Viersen in Germany.

Large areas of the county are extremely low-lying and Holme Fen is notable for being the UK's lowest physical point at 2.75 m (9 ft) below sea level. The highest point is in the village of Great Chishill at 146 m (480 ft) above sea level. Other prominent hills are Little Trees Hill and Wandlebury Hill in the Gog Magog Downs, Rivey Hill above Linton, Rowley's Hill and the Madingley Hills.

Due to its flat terrain and proximity to the continent, many airfields were built for RAF Bomber Command, RAF Fighter Command, and the USAAF during the Second World War. In recognition of this, the only American Second World War burial ground in England is Cambridge American Cemetery and Memorial, located between Coton and Madingley.

The National Gazetteer of Great Britain and Ireland (1868), states that:

'Cambridgeshire is not the seat of any important manufactures and has no weaving trades. In some districts baskets and reed mats are made; but the chief occupations of the inhabitants are agriculture, cattle rearing, brewing, and malting. Brick-making is carried on to a considerable extent, the county being deficient of stone for building; and there are a considerable number of ship, boat, and barge builders; also millers, tanners, curriers, and shoemakers, who manufacture not only for home consumption but for exportation. There are paper-mills, parchment works, a needle factory, ball-cotton factory, and large printing establishments, chiefly at Cambridge, employing above 300 persons, a great number of erudite books being annually printed at the University press.'

The National Gazetteer also describes Huntingdonshire, historic county and now a district of Cambridgeshire, as:

'HUNTINGDONSHIRE, (or Hunts), an inland county of England, situated in the east lowlands, between 52° 8' and 52° 36' north lat., and 0° 3' east and 0° 30' west long. In shape it somewhat resembles a lozenge, being 30 miles in length from north to south, and about 23 miles in its shorter diagonal from east to west. In size it is one of the smallest of the English counties, only Middlesex and Rutland being less, and one only, Rutland, having fewer inhabitants.'
