South Leicestershire is a constituency represented in the House of Commons of the UK Parliament since 2015 by Alberto Costa, a member of the Conservative Party.

1832–1885: The Hundreds of Gartree (excluding the parishes of Baggrave, Burrough, Knossington, Marefield, Pickwell-cum-Leesthorpe, Ouston, and Newbold-Saucey), Sparkenhoe and Guthlaxton, and the Borough of Leicester and the Liberties thereof.

Nearby is the former site of RAF Bitteswell, since redeveloped as Magna Park, one of the largest distribution centres in Europe.

Both divisions of the county were abolished by the Redistribution of Seats Act 1885 for the 1885 general election, when they were replaced by four new single-seat constituencies: Bosworth, Harborough, Loughborough and Melton.

Prominent members in this period included Thomas Paget (Jnr) (1807–1892) who followed the footsteps of his father in this role (his father having represented Leicestershire) and as partner in Leicester Bank, and Albert Pell, a member of a group of MPs, which included Henry Chaplin, Sir Massey Lopes and Clare Sewell Read, who supported farming interests.
