Barnsley West and Penistone was a parliamentary constituency in South Yorkshire which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first-past-the-post voting system.

It was considered a safe seat for the Labour Party.

The Metropolitan Borough of Barnsley wards of Darton, Dodworth, Hoyland East, Hoyland West, Park, Penistone East, Penistone West, and Worsbrough.

Barnsley West and Penistone constituency was created in 1983 when the former Barnsley constituency was split into three divisions. This seat also contained parts of the former Penistone constituency, which was abolished in the same boundary review: in total it covered the western part of the Borough of Barnsley and included the town of Penistone. It bordered the constituencies of Sheffield Hillsborough, Wentworth, Barnsley East and Mexborough, Barnsley Central, Hemsworth, Wakefield, Colne Valley, and High Peak. Penistone itself provides the highest Conservative vote in the Borough of Barnsley (although not always a majority - see for instance 1998 Barnsley Council election and 2008 Barnsley Council election), but the other small towns and villages, mostly former mining areas, are safely Labour.

The constituency had two Members of Parliament, both of which were from the Labour Party or Labour Co-operative.
