North East Derbyshire is a constituency represented in the House of Commons of the UK Parliament since 2017 by Lee Rowley of the Conservative Party. This is the first time a Conservative MP has won this seat since 1935.

The seat was created in the Redistribution of Seats Act 1885. Until 1910, the area was regularly represented by a Liberal MP. From 1935 until 2017, N.E. Derbyshire had always returned a Labour candidate as MP. In 2010, the result meant the seat became marginal, and this continued in 2015. The runner-up candidate since 1945 has been a Conservative. The 2015 result gave the seat the 17th-smallest majority of Labour's 232 seats by percentage of majority. The seat was subsequently a gain for the Conservatives in the 2017 election with Lee Rowley having a majority of 5.7%. Rowley is the first Conservative MP to be returned for the seat in over 80 years.

In line with nationwide swing in 2015, UKIP fielded a candidate who won more than 5% of the vote therefore kept their deposit; the Liberal Democrat candidate forfeited their deposit in 2015. The Green Party fielded a candidate for the first time in 2015; the party's Kesteven forfeited his deposit.

Turnout has ranged from 58.9% in 2001 to 86.4% in 1950.

In the 20th century mining and associated industries were an important source of employment and primary industries for the wider economy, though the former ceased around 1970. At about the same time, some ex-mining towns like Dronfield saw much middle class commuter house building in areas like Dronfield Woodhouse; jobs were typically in Sheffield and Chesterfield.
