Wortley Hall is a former stately home in the small South Yorkshire village of Wortley, located south of Barnsley, England. For more than six decades the hall has been owned by individual members and organisations associated with the British trade union and wider labour movement. It is currently used by several trades unions and other organisations as a venue for residential training courses and other meetings, as well as for purely social gatherings and is run as a non profit co-operative. The building is constructed of sandstone ashlar with graduated slate roofs to an irregular floor plan, mostly in 2 storeys with a 7-bay south front. The hall is a licensed venue for wedding and civil partnership ceremonies, and is open to day visitors who wish to explore its formal gardens and extensive grounds.

The builder of this section was John Platt of Rotherham. Montagu left the Wortley Hall estate to his daughter Mary. In 1735 she had eloped with John Stuart, 3rd Earl of Bute, who later became Prime Minister. From her it passed in 1794 to their son, Colonel James Archibald Stuart (1747–1818), who added the surname Wortley to his own and later also added Mackenzie. He left the estate to his son Colonel James Archibald Stuart-Wortley-Mackenzie (1776–1845) who was one of the two MPs for Yorkshire from 1818 to 1826, when he was created Baron Wharncliffe. Edward Montagu-Stuart-Wortley-Mackenzie, 3rd Baron Wharncliffe was created Earl of Wharncliffe in 1876. The Hall was the seat of the Earls of Wharncliffe until the Second World War, when it was
