# Parliamentary representation from Derbyshire

The historic county of Derbyshire, located in the 21st century region of East Midlands, was represented in Parliament from the 13th century. This article provides a list of constituencies constituting the Parliamentary representation from Derbyshire.
In 1889 Derbyshire became an administrative county and in 1974 much the same area became a shire county. Derby became a unitary authority in 1997, but it remains part of the ceremonial county of Derbyshire.
The first part of this article covers the constituencies wholly or predominantly within the area of the historic county of Derbyshire, both before and after the administrative changes of 1889 and 1974. The second part refers to constituencies mostly in another historic county, which included some territory from the historic county of Derbyshire (if any). The summaries section only refers to the constituencies included in the first section of the constituency list.
