Farnworth was a county constituency in Lancashire which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom from 1918 until it was abolished for the 1983 general election.
From 1885 to 1918 the Farnworth area had been included in the Radcliffe-cum-Farnworth constituency.
The Farnworth constituency included Farnworth, Moses Gate, Kearsley, Stoneclough, Little Lever, Little Hulton, Walkden, and Roe Green.
The constituency disappeared in the 1983 redistribution; Farnworth itself and the surrounding wards within the Metropolitan Borough of Bolton were placed in the new Bolton South East constituency (1983-2024), while Walkden, Worsley and surroundings in the City of Salford became part of the new Worsley (1983âÂÂ2010), later Worsley and Eccles South constituency up to 2024.
As of the 2024 General Election, both the towns of Farnworth and Walkden and their environs, are now once again in the same constituency, now known as Bolton South and Walkden, while Worsley itself remains part of a modified Worsley and Eccles constituency.
