South Lancashire, formally called the Southern Division of Lancashire or Lancashire Southern, is a former county constituency of the South Lancashire area in England. It returned two Members of Parliament (MPs) to the British House of Commons from 1832 to 1861, and then from a very narrow reform of that year, three until it was further split in 1868.
The constituency was created by the Great Reform Act of 1832 by the splitting of Lancashire constituency into Northern and Southern divisions. It was abolished by the Second Reform Act of 1867.
