South Derbyshire constituency covers Derbyshire to the south of the city of Derby, forming a tapering salient surrounded by Staffordshire and Leicestershire.

The constituency was originally created after the Reform Act in 1832 when Derbyshire was divided into North Derbyshire and South Derbyshire.

The present constituency was created in 1983 from parts of the seats of Derby North, Derby South, Belper, and South East Derbyshire. When Parliament implemented the plans of the Boundary Commission's Fourth Periodic Review of Westminster constituencies 1995 that came into effect for 1997, Mickleover ward was transferred to Derby South. Under the Fifth Periodic Review of Westminster constituencies, approved for the 2010 general election, the constituency shed the two City of Derby wards to become coterminous with its district.
