Huntingdonshire, an inland county of England, bordering on Cambridgeshire, Northamptonshire, and Bedfordshire; area, 359 sq. m., being the smallest county of England except Rutland and Middlesex; pop. in 1871, 63,672. The N. portion forms part of the fen district (see Bedford Level), and is devoted chiefly to grazing. In the W. and S: parts the surface is slightly varied by the swell of two low ridges of hills. In the S. E. is an extensive plain of fertile land, and along the banks of the Ouse and Nene are rich meadows overflowed at high tides. The general character of the soil is either gravelly or clayey loam. Although the greater part of the county was once a royal forest, it is now very bare of timber. Agriculture is the only industry. The products are wheat, oats, and beans, with some barley, hops, hemp, turnips, and mustard seed. The chief rivers are the Ouse within the county, and the Nene along the border, with their tributaries. There were formerly several small meres or shallow lakes in the county, but these have all been drained and brought under cultivation. The principal towns are Huntingdon, St. Ives, St. Neots, and Ramsay. Huntingdon is on the Ouse, 59 m.

N. of London; pop. of the municipal borough in 1871, 4,243. It was the birthplace of Oliver Cromwell.
