Liversedge is an industrial town in the Kirklees district, in West Yorkshire, England. Historically part of the West Riding of Yorkshire, Liversedge lies between Cleckheaton and Heckmondwike. The Kirklees ward is now called Liversedge and Gomersal with a population at the 2011 Census of 19,420. Liversedge forms part of the Heavy Woollen District and was historically part of the parish of Birstall.

Liversedge comprises several settlements that are all distinctive. Norristhorpe clings to one side of the Spen Valley, looking over the town of Heckmondwike. Roberttown is on the opposite side of the A62. Millbridge is the geographical centre of Liversedge and, with the neighbouring village of Flush, is the place the mills of the woollen industry stood. Towards Cleckheaton are Hightown, Littletown and Popeley Hill.

Liversedge has a Wakefield postcode (WF15). Some areas have a Wakefield dialling code (01924) while others have a Bradford dialling code (01274).

Liversedge is recorded in the Domesday Book as Livresec, a manor belonging to Radulf, a vassal of Ilbert de Lacy. There are two possible etymologies for the name: from the Old English Lēofheres-ecg meaning 'a ridge or edge belonging to Lēofhere'; or, alternatively, the first element could have originally been *Lēfer-, related to the Old English word lifer used in the sense of 'thick clotted water', and the second element secg, 'a bed of reeds or rushes'.

In the 15th century, the lord of the manor was a member of the Neville family and Liversedge was already involved in woollen manufacture. The trade grew and by the 19th century the town was busy in the manufacture of woollen goods. In 1812, the town was the scene of a Luddite attack on Rawfolds Mill when approximately two hundred armed weavers, croppers and other artisans attempted to destroy cropping frames at a mill operated by William Cartwright. Two Luddites were killed and some were injured by four soldiers and armed workmen defending the mill, with no losses on Cartwright's side. Liversedge Town Hall at the top of Knowler Hill was built for Liversedge Local Board and completed in around 1880.

In 2012, Sparrow Park was constructed outside Liversedge Town Hall in commemoration of the 200th anniversary of the uprising and attack on Rawfolds Mill, which began just up the road from the monument in the still-operational "Shears" pub.

Liversedge has a church that was built at the time of the Battle of Waterloo. Healds Hall, formerly the Spenborough Museum, is now a hotel. In the days of Charlotte Brontë it was home to Hammond Roberson whom she transformed into the Reverend Matthewman Helstone in her novel Shirley.

Spen Beck runs through Liversedge.
