North Derbyshire was a Parliamentary constituency in the United Kingdom constituencies. It originally returned two Knights of the Shire to the House of Commons of the Parliament of the United Kingdom. The constituency was created when Derbyshire constituency was split into North Derbyshire and South Derbyshire under the 1832 Reform Act. It was abolished in 1885, together with the constituencies of South Derbyshire and East Derbyshire. In 1885 the area of the three constituencies was split between the new smaller constituencies of Chesterfield, Mid Derbyshire, North-East Derbyshire, South Derbyshire, West Derbyshire, High Peak and Ilkeston.
