Worsley is a town in the City of Salford in Greater Manchester, England, which in 2014 had a population of 10,090. It lies along Worsley Brook, 5.75 miles (9.25 km) west of Manchester. The M60 motorway bisects the area.

Historically part of Lancashire, there is evidence of Roman and Anglo-Saxon activity, including two Roman roads. The completion in 1761 of the Bridgewater Canal allowed Worsley to expand from a small village of cottage industries to an important town based upon cotton manufacture, iron-working, brick-making and extensive coal mining. Later expansion came after the First and Second World Wars, when large urban estates were built.

Worsley Delph is a scheduled monument and a significant part of the town's historic centre is now a conservation area.

Worsley Village was in 1969 designated as a conservation area by the former Lancashire County Council. Bisected by the A572 Worsley Road, the area covered about 34.25 acres of land and included 40 listed buildings, such as the Packet House, a telephone kiosk, and the Delph sluice gates, but this list has since increased to 48 listed buildings.[48] Much of the area around the canal and Worsley Delph was restored and landscaped between 1966 and 1967 by the Worsley Civic Trust and the local council, ready for a visit by Elizabeth II on 17 May 1968. As the canal passes through Worsley, iron oxide from the mines has, for many years, stained the water bright orange. The removal of this colouration is the subject of a remedial scheme, which was completed in 2004. This has not been successful and as of 2017 much of the canal centered on the Delph is still bright orange.

Wardley Hall is an early medieval manor house and a Grade I listed building in Wardley. The current hall dates from around 1500 but was extensively rebuilt in the 19th and 20th centuries. Worsley Old Hall is a Grade II listed building near Walkden Road. The Post Medieval building is said to have been moated, but no signs of the moat now remain.

Parts of Worsley are currently being considered as World Heritage Sites. The area includes Worsley Delph (itself a scheduled monument), parts of Worsley Green, and the Bridgewater Canal.

In 2015, the Royal Horticultural Society announced plans for a restoration of the garden at Worsley New Hall, to open in 2019 under the name RHS Garden Bridgewater.
