Northamptonshire (UK Parliament constituency)

The county constituency of Northamptonshire, in the East Midlands of England was a constituency of the House of Commons of the Parliament of England, then of the Parliament of Great Britain from 1707 to 1800 and of the Parliament of the United Kingdom from 1801 to 1832 and was represented in Parliament by two MPs, traditionally known as Knights of the Shire.

After 1832 the county was split into two new constituencies, North Northamptonshire and South Northamptonshire.

Boundaries
The constituency consisted of the historic county of Northamptonshire. Although the county contained a number of parliamentary boroughs, each of which elected one or two MPs in its own right for parts of the period when Northamptonshire was a constituency, these areas were not excluded from the county constituency. Owning freehold property of the required value, within such boroughs, could confer a vote at the county election. (After 1832, only non-resident owners of forty shilling freeholds situated in borough seats could qualify for a county vote on the basis of that property.)
