Derby regularly sent two representatives to Parliament from Edward I's reign. In 1900 it was one of the first two constituencies to elect a member from the then newly formed Labour Party, along with Merthyr Tydfil.

In 1950 the constituency was abolished and replaced by the two single-member constituencies of Derby North and Derby South.
