Derbyshire is a former United Kingdom Parliamentary constituency. It 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. It was represented by two Knights of the Shire.

The constituency, which first returned members to Parliament in 1290, consisted of the historic county of Derbyshire. (This included the borough of Derby; even though Derby elected two MPs in its own right, it was not excluded from the county constituency, and owning property within the borough could confer a vote at the county election.)

In medieval times, the MPs would have been elected at the county court, by the suitors to the court, which meant the tiny handful of the local nobility who were tenants in chief of the Crown. However, from 1430, the Forty Shilling Freeholder Act extended the right to vote to every man who possessed freehold property within the county valued at £2 or more per year for the purposes of land tax; it was not necessary for the freeholder to occupy his land, nor even in later years to be resident in the county at all.

Except briefly during the period of the Commonwealth, Derbyshire had two MPs elected by the bloc vote method, under which each voter had two votes. (In the First and Second Parliaments of Oliver Cromwell's Protectorate, there was a general redistribution of seats and Derbyshire elected four members; the traditional arrangements were restored from 1659.)
