Chorley Constituency Labour Party is the Labour Party’s organisational unit for the Chorley Parliamentary Constituency.

Chorley is located at the foot of the West Pennine Moors and is overlooked by Healey Nab, a small hill which is part of the West Pennine Moors. It is the seat for the Borough of Chorley which is made up of Chorley and its surrounding villages. Chorley had a population of 33,424 as of the 2001 census, with the wider borough of Chorley having a population of 101,991. Chorley forms a conurbation with Preston and Leyland and was once proposed as being designated part of the Central Lancashire New Town under the New Towns Act, a proposal which was eventually scaled back.

The town was vital during World War II as it was home to the Royal Ordnance Factory, a large munitions factory in the village of Euxton around 2 miles outside the town centre. With a second smaller factory also built near the Blackburn-Wigan railway line in Heapey.

As the 21st century progresses, Chorley will grow significantly in size as the new Buckshaw Village gets built on the former explosives area of the ROF Chorley site, the old munitions factory at Euxton.

Chorley saw the completion of the largest Mormon temple in Europe in 1998, known as the Preston England Temple.

Under the Local Government Act 1972, Chorley became the core of a larger non-metropolitan district on 1 April 1974. The present Borough of Chorley has forty-seven councillors, representing twenty electoral wards.
